Paul is comparing the cost of cell phone services. At CellCoA, the phone he wants costs $305 and the unlimited calling plan costs $45 per
month. At CellCoB, Paul can purchase the same phone for $350 and get an unlimited calling plan for $30 per month. In how many months
will both plans cost the same?
These equations, which are graphed below, represent the situation.
y = 45x + 305
y= 30x + 350
Here, x represents the
number of months and y represents the amount paid.

Answer:

[tex]x = \frac{ - 19}{3} [/tex]

Step-by-step explanation:

[tex]( - 5x + 5) + ( - 7x + 9) = 90[/tex]

[tex] = > 5 - 5x - 7x + 9 = 90[/tex]

[tex] = > 14 - 12x = 90[/tex]

[tex] = > - 12x = 90 - 14[/tex]

[tex] = > - 12x = 76[/tex]

[tex] = > x = \frac{76}{ - 12} = \frac{ - 19}{3} [/tex]

Answer:

m∠XYZ = 162°

Step-by-step explanation:

We can see that ∠XYZ is an exterior angle while ∠W and ∠X are the opposite interior angles.

We know that the exterior angle of triangle is equal to the sum of opposite interior angles

Given

m∠XYZ = (15x-18)°

m∠W = (5x+2)°

m∠X = (8x+4)°

Mathematically it can be written as:

m∠X+m∠W = m∠XYZ

[tex]8x+4+5x+2 = 15x-18\\13x+6 = 15x-18\\13x-15x = -18-6\\-2x = -24\\\frac{-2x}{-2} = \frac{-24}{-2}\\x = 12[/tex]

Putting x=12 in m∠XYZ

[tex]15x-18\\=15(12)-18\\=180-18=162[/tex]

Hence,

m∠XYZ = 162°

Answer

418.2 m

Step-by-step explanation:

The first thing you need to realize to simplify the solving of this question for yourself is that since 5 cm are equal to 25 m, you can convert that into 1 cm is equal to 5 m. With that in mind, you then want to find the area of the rectangle in cm, which would be 6.8 times 12.3, which comes out to be 83.64. All you need to do from there is multiply that by 5, which should give you the answer of 418.2

Answer:

6555

Step-by-step explanation:

Again you can you Distributive property to answer this question here is how-To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Answer:

Undefined slope

Step-by-step explanation:

To calculate the slope between two points, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

The formula for the slope m between points (x₁, y₁) and (x₂, y₂) is: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] , which is also known as "rise over run".

Here, we have the points (-9, 3) and (-9, 2).

x₁ = -9,  y₁ = 3,  x₂ = -9,  y₂ = -2. We can plug these values in to the "rise over run" equation:

[tex]m=\frac{-2-3}{-9-(-9)}[/tex]

[tex]m=\frac{-5}{0}[/tex]

This is a vertical line.

The slope of a line cannot be undefined (a vertical line), because the x-coordinate never changes no matter what the y-coordinate is. Thus, the slope is undefined for the line passing between these two points.

Answer:

Step-by-step explanation:

Simplifying

2g = W

Solving

2g = W

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Divide each side by '2'.

g = 0.5W

Simplifying

g = 0.5W

Answer:x=2, x=2.5

Step-by-step explanation:

5x+1=11

Subtract 1 from each side

5x=10

Divide each side by 5

x=2

2x-3=2

Add 3 to each side

2x=5

Divide each side by 2

x=2.5

Answer:a)2 .(b) 2.5

Step-by-step explanation:

a) 5x + 1 = 11

Substract 1 from both sides

5x + 1 - 1 = 11 - 1

5x = 10

x = 10/5

x = 2.

b). 2x - 3 = 2

Add 3 to both sides

2x - 3 + 3 = 2 +3

2x = 5

x = 5/2

x = 2.5

7436 ÷ 13 = 572

Answer: m angle 1=164°

Step-by-step explanation:

Since the two provided angles are congruent we can make the equation

4x-20=3x-11

Subtract 3x from each side

x-20=-11

Add 20 to each side

x=9

now apply our x to one of the angles

4(9)-20

36-20

16

In a parellelogram all sides added up =360° so if we subtract 16•2 from 360 we can get the sun of the two remaining angles. So 360-32 is 328°. Divide that by 2 to get the angle measure of one of the two angles. 164

Answer:

I think this is it.....If not let me know

2x - y = 3

Slope = 2

x - intercept = 3/2 = 1.50000

y - intercept = 3/-1 = -3.0000

x + y = 0

Slope = -2.000/2.000 = -1.000

x - intercept = 0/1 = 0.0000

y - intercept = 0/1 = 0.0000

Answer:

21

Step-by-step explanation:

The area of a triangle is base times height divided by two. Your base, which happens to be on top, goes from -4 to 3, or 7 units. The height goes from 3 to -3, or 6 units. 6 times 7 is 42, and 42/2= 21

20. 7/9 (seven ninths)

Explanations

There are nine letters.

There is one T.

There are 4 E's.

There are two N's.

There are two S's.

15. You know that there are two S's. Two S's out of nine total letters is 2/9. The probability that an S is selected is 2/9.

16. A consonant is a letter that is not a vowel. The consonants in TENNESSEE are T, N, and S. There is one T, two N's, and two S's, meaning there are 5 consonants. Five consonants out of nine total letters is 5/9. The probability that a consonant is selected is 5/9.

17. You know that there is one T and two N's. This is a total of three letters. The probability of getting on of these three letters is 3/9. 3/9 simplified is 1/3. The probability of selecting a T or N is 1/3.

18. You know that there are no V's in TENNESSEE. Therefore, no matter what letter you select, there is a 100% chance you'll get a number that is not V. All nine letters are not the letter V, so the probability of selecting a letter that is not V is 1/1 or 1.

19. You know that there are no W's in TENNESSEE either. Therefore, whichever letter you select, you will not get a W. The chance of selecting a W is 0/9 or 0.

20. There are four S's. That means there are five letters that are not S. These are: T, N, N, S, S. Five letters out of nine letters in total is 5/9. The probability of selecting a number that is not S is 5/9.

Answer:

Base = 10 cm

Height = 60 cm

Step-by-step explanation:

The formula for the area of a triangle is  [tex]area=\frac{1}{2} *b*h[/tex] , where b is the length of the base of the triangle, and h is the length of the height of the triangle.

We know the area is 300, and since the height of the triangle is 6 times its base, we know that [tex]h=6*b[/tex]. We can plug in these values into our formula for the area of a triangle, which gives us the following equation to solve:

[tex]300=\frac{1}{2} *b*(6*b)[/tex]

[tex]3b^2=300[/tex]

[tex]b=\sqrt{100} =10[/tex]

The base of the triangle is 10 centimeters.

Now that we know the base of the triangle, we can plug its value in to the original formula to solve for the height of the triangle, which gives us the following equation:

[tex]300=\frac{1}{2} *10*h[/tex]

[tex]5h=300[/tex]

[tex]h=60[/tex]

The height of the triangle is 60 centimeters.
