In the given diagram, we have a triangle with two angles labeled as (3x + 10)° and (4x - 30)°. We need to solve for the value of x.

To find the value of x, we can use the property that the sum of the interior angles of a triangle is always 180 degrees. Therefore, we can set up the equation:

(3x + 10) + (4x - 30) + 90 = 180

Let's simplify the equation step by step:

Combine like terms:

3x + 4x + 10 - 30 + 90 = 180

7x + 70 = 180

Next, isolate the variable term by subtracting 70 from both sides:

7x + 70 - 70 = 180 - 70

7x = 110

To solve for x, divide both sides of the equation by 7:

(7x)/7 = 110/7

x = 15.71

Therefore, the value of x is approximately 15.71.

Please note that this solution assumes the given diagram accurately represents the angle measurements, and the calculations provided are based on that assumption.

Issa invested $2600 at a 4 percent interest rate and $3300 at a 10 percent interest rate.

Let's assume Issa invests x dollars at a 4 percent interest rate and y dollars at a 10 percent interest rate.

The equation that describes the total investment is:

x + y = 5900

The equation that describes the interest earned is:

0.04x + 0.1y = 434

To solve this system of equations, we can use substitution or elimination method. Here, we'll use the substitution method.

From the first equation, we can express x in terms of y:

x = 5900 - y

Substituting this value of x into the second equation, we have:

0.04(5900 - y) + 0.1y = 434

Now, let's solve this equation to find the value of y:

0.04(5900 - y) + 0.1y = 434

236 - 0.04y + 0.1y = 434

0.06y = 198

y = 198 / 0.06

y = 3300

Now that we have the value of y, we can substitute it back into the first equation to find x:

x + 3300 = 5900

x = 5900 - 3300

x = 2600

Therefore, Issa invested $2600 at a 4 percent interest rate and $3300 at a 10 percent interest rate.

37.5 seconds is equivalent to 0.625 minutes for the battery to discharge from 15% to 0% with a discharge rate of 0.12% every 30 seconds.

To calculate how long a battery will last when it discharges at a rate of 0.12% per 30 seconds, we can set up a proportion based on the given information.

Let's assume the battery has a total charge of 100%. We want to find out how long it takes for the battery to discharge from 15% to 0%, given a discharge rate of 0.12% every 30 seconds.

First, let's determine the proportion:

(0.12% / 30 seconds) = (15% / x sec

To solve for x (the time it takes for the battery to discharge from 15% to 0%), we can cross-multiply:

0.12% × x = 30 seconds × 15%

Now, let's solve for x:

0.0012 × x = 0.3 × 15%

0.0012 × x = 0.045

Divide both sides by 0.0012:

x = 0.045 / 0.0012

x ≈ 37.5

Therefore, it would take approximately 37.5 seconds for the battery to discharge from 15% to 0% with a discharge rate of 0.12% every 30 seconds.

To convert 37.5 seconds into minutes, we divide the number of seconds by 60 (since there are 60 seconds in a minute).

37.5 seconds / 60 = 0.625 minutes

Therefore, 37.5 seconds is equivalent to 0.625 minutes.

The length of the rectangle is about 12.37 feet.

We are given that;

Width= 4 feet

Diagonal length= 13feet

Now,

The width and length of the rectangle are the legs and the diagonal is the hypotenuse. We can label them as:

w = 4 (width) l = ? (length) d = 13 (diagonal)

Plugging these values into the Pythagorean theorem, we get:

w^2 + l^2 = d^2 4^2 + l^2

Answer:

5) El precio del petróleo en los dos últimos días tuvo las siguientes fluctuaciones: aumentó un 3,5% en el primer día y luego bajó un 2% en el último día. Si el valor final es de U$S 68, ¿cuál era el valor inicial?

La solución al problema matemático es la siguiente:

Supongamos que el valor inicial del petróleo es x. En el primer día, el precio aumentó en un 3,5%, por lo que el nuevo precio es x + 0.035x = 1.035x. En el segundo día, el precio disminuyó en un 2%, por lo que el precio final es 1.035x - 0.02(1.035x) = 0.98(1.035x) = 1.0143x.

Dado que sabemos que el precio final es de U$S 68, podemos establecer una ecuación para resolver x: 1.0143x = 68.

Resolviendo para x, obtenemos x = 68/1.0143 ≈ U$S 67.04.

Entonces, el valor inicial del petróleo era aproximadamente U$S 67.04.

Answer:

We can start by using the second equation to eliminate x:

2x + 5y - 2z = 3

2x = -5y + 2z + 3

x = (-5/2)y + z + 3/2

Now we can substitute this expression for x into the first and third equations:

x + y + z = 4

(-5/2)y + z + 3/2 + y + z = 4

(-5/2)y + 2z = 5/2

x + 7y - 7z = 5

(-5/2)y + z + 3/2 + 7y - 7z = 5

(9/2)y - 6z = 7/2

Now we have a system of two equations with two variables, (-5/2)y + 2z = 5/2 and (9/2)y - 6z = 7/2. We can use any method to solve for y and z, such as substitution or elimination. However, we will find that the system is inconsistent, meaning there is no solution that satisfies both equations.

Multiplying the first equation by 9 and the second equation by 5 and adding them, we get:

(-45/2)y + 18z = 45/2

(45/2)y - 30z = 35/2

Adding these two equations, we get:

-12z = 40/2

-12z = 20

z = -5/3

Substituting z = -5/3 into (-5/2)y + 2z = 5/2, we get:

(-5/2)y + 2(-5/3) = 5/2

(-5/2)y - 10/3 = 5/2

(-5/2)y = 25/6

y = -5/12

Substituting y = -5/12 and z = -5/3 into any of the original equations, we get:

x + y + z = 4

x - 5/12 - 5/3 = 4

x = 29/12

Therefore, the solution is (x, y, z) = (29/12, -5/12, -5/3). However, if we substitute these values into any of the original equations, we will find that it does not satisfy the equation. For example:

2x + 5y - 2z = 3

2(29/12) + 5(-5/12) - 2(-5/3) = 3

29/6 - 5/2 + 5/3 ≠ 3

Since there is no solution that satisfies all three equations, the system is inconsistent.

Step-by-step explanation:

Answer:

See below for proof.

Step-by-step explanation:

A system of equations is not consistent when there is no solution or no set of values that satisfies all the equations simultaneously. In other words, the equations are contradictory or incompatible with each other.

Given system of equations:

[tex]\begin{cases}x+y+z = 4\\2x+5y-2z =3\\x+7y-7z =5\end{cases}[/tex]

Rearrange the first equation to isolate x:

[tex]x=4-y-z[/tex]

Substitute this into the second equation to eliminate the term in x:

[tex]\begin{aligned}2x+5y-2z&=3\\2(4-y-z)+5y-2z&=3\\8-2y-2z+5y-2z&=3\\-2y-2z+5y-2z&=-5\\5y-2y-2z-2z&=-5\\3y-4z&=-5\end{aligned}[/tex]

Subtract the first equation from the third equation to eliminate x:

[tex]\begin{array}{cccrcrcl}&x&+&7y&-&7z&=&5\\\vphantom{\dfrac12}-&(x&+&y&+&z&=&4)\\\cline{2-8}\vphantom{\dfrac12}&&&6y&-&8z&=&1\end{aligned}[/tex]

Now we have two equations in terms of the variables y and z:

[tex]\begin{cases}3y-4z=-5\\6y-8z=1\end{cases}[/tex]

Multiply the first equation by 2 so that the coefficients of the variables of both equations are the same:

[tex]\begin{cases}6y-8z=-10\\6y-8z=1\end{cases}[/tex]

Comparing the two equations, we can see that the coefficients of the y and z variables are the same, but the numbers they equate to is different. This means that there is no way to add or subtract the equations to eliminate one of the variables.

For example, if we subtract the second equation from the first equation we get:

[tex]\begin{array}{crcrcl}&6y&-&8z&=&-10\\\vphantom{\dfrac12}-&(6y&-&8z&=&\:\:\;\;\:1)\\\cline{2-6}\vphantom{\dfrac12}&&&0&=&-11\end{aligned}[/tex]

Zero does not equal negative 11.

Since we cannot eliminate the variable y or z, we cannot find a unique solution that satisfies all three equations simultaneously. Therefore, the system of equations is inconsistent.

Answer:

∠ 3 = 35° , ∠ 7 = 145° , ∠ 8 = 35° , ∠ 5 = 145°

Step-by-step explanation:

∠ 3 and ∠ 1 are vertically opposite angles and are congruent , then

∠ 3 = 35°

-----------------

∠ 3 and ∠ 5 are same- side interior angles and sum to 180°, that is

∠ 5 + ∠ 3 = 180°

∠ 5 + 35° = 180° ( subtract 35° from both sides )

∠ 5 = 145°

------------------

∠ 5 and ∠ 7 are vertically opposite angles and are congruent , then

∠ 7 = 145°

--------------

∠ 1 and ∠ 8 are corresponding angles and are congruent , then

∠ 8 = 35°

---------------

The correct graph is A.

The first equation is y = -3/4x + 2. This can be rewritten as y - 2 = -3/4x. Solving for x, we get x = (4/3)(y - 2).

The second equation is y = -1/2x - 1. This can be rewritten as y + 1 = -1/2x. Solving for x, we get x = -2(y + 1).

The two lines intersect at the point (0, 2). Plugging in x = 0 into both equations, we get y = 2 for both equations. Therefore, the two lines must intersect at the point (0, 2).

The slope of the first line is -3/4. The slope of the second line is -1/2. The slopes are negative inverses of each other. Therefore, the two lines are perpendicular.

A coordinate grid with one line that passes through the points 0 comma 2 and 4 comma negative 1 and another line that passes through the points 0 comma negative 1 and 1 comma negative 3 is incorrect because the two lines are not perpendicular.

A coordinate grid with one line that passes through the points 0 comma 2 and 3 comma negative 2 and another line that passes through the points 0 comma negative 1 and negative 1 comma 1 is incorrect because the two lines intersect at the point (0, 2).

A coordinate grid with one line that passes through the points 0 comma 2 and 3 comma negative 2 and another line that passes through the points 0 comma negative 1 and 2 comma negative 2 is incorrect because the two lines are not perpendicular.

Answer: x = 101, y = 20

From corresponding angles, as both pairs of lines are parallel, we know that 79 is the supplement of x. That means 79 + x = 180.

From this we have x = 101 degrees.

From corresponding angles, x is the supplement of ( 4y - 1 )

Since we know x = 101, we can plug it into our equation:

4y - 1 + 101 = 180

Simplifying:

4y + 100 = 180

Subtracting 100 from both sides of the equation:

4y = 80

Dividing by 4:

y = 20

Hope this helps!
