Answer:

x = 10/9

Step-by-step explanation:

Solve for x:

(4 x)/5 + 4/3 = 2 x

Put each term in (4 x)/5 + 4/3 over the common denominator 15: (4 x)/5 + 4/3 = (12 x)/15 + 20/15:

(12 x)/15 + 20/15 = 2 x

(12 x)/15 + 20/15 = (12 x + 20)/15:

(12 x + 20)/15 = 2 x

Multiply both sides by 15:

(15 (12 x + 20))/15 = 15×2 x

(15 (12 x + 20))/15 = 15/15×(12 x + 20) = 12 x + 20:

12 x + 20 = 15×2 x

15×2 = 30:

12 x + 20 = 30 x

Subtract 30 x from both sides:

(12 x - 30 x) + 20 = 30 x - 30 x

12 x - 30 x = -18 x:

-18 x + 20 = 30 x - 30 x

30 x - 30 x = 0:

20 - 18 x = 0

Subtract 20 from both sides:

(20 - 20) - 18 x = -20

20 - 20 = 0:

-18 x = -20

Divide both sides of -18 x = -20 by -18:

(-18 x)/(-18) = (-20)/(-18)

(-18)/(-18) = 1:

x = (-20)/(-18)

The gcd of 20 and -18 is 2, so (-20)/(-18) = (-(2×10))/(2 (-9)) = 2/2×(-10)/(-9) = (-10)/(-9):

x = (-10)/(-9)

Multiply numerator and denominator of (-10)/(-9) by -1:

Answer: x = 10/9

Answer:

[tex]f(-8)=-2[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=\frac{x}{4}[/tex]

And we want to find f(-8).

So, simply substitute -8 for x. This yields:

[tex]f(-8)=\frac{-8}{2}[/tex]

Divide:

[tex]f(-8)=-2[/tex]

Hence, our answer is -2.

Answer:

D) 117

Step-by-step explanation:

All angles of a triangle will always add up to 180 degrees. Thus, 22 + 41 = 63, 180 - 63 = 117.

you can eliminate A and D because grades are distributed by 100. and c only has 4.85 when the question says she made a 48.5

Answer:

[tex]Chocolate\ Weight = \frac{2}{3}kg[/tex]

Step-by-step explanation:

Given

[tex]Candies =2\frac{2}{3}\ kg[/tex]

[tex]Chocolate = \frac{1}{4}[/tex] of the candies

Required

Determine the weight of the chocolate pretzels ---- This completes your question

To determine the weight, we simply multiply the fraction of chocolates by the total weight of the candies.

i.e.

[tex]Chocolate\ Weight = \frac{1}{4} * 2\frac{2}{3}[/tex]

Convert Fraction

[tex]Chocolate\ Weight = \frac{1}{4} * \frac{8}{3}[/tex]

[tex]Chocolate\ Weight = \frac{1 * 8}{4 * 3}[/tex]

[tex]Chocolate\ Weight = \frac{8}{12}[/tex]

Simplify

[tex]Chocolate\ Weight = \frac{2}{3}kg[/tex]

Answer:

a) s = -16[tex]t^{2}[/tex] + 192t + 96

b) Height of the football after 2 seconds is 448 feet.

ii. The football would not hit the ground after 2 seconds.

Step-by-step explanation:

Given:

s = -16[tex]t^{2}[/tex] + [tex]V_{o}[/tex]t + [tex]s_{o}[/tex]

where: s is the height of the football above the ground, t is the time, [tex]V_{o}[/tex] is the initial velocity and [tex]s_{o}[/tex] is the initial height.

The height of the building = [tex]V_{o}[/tex] = 192 feet and the initial speed of the ball = [tex]s_{o}[/tex] = 96 feet per second, then;

s = -16[tex]t^{2}[/tex] + 192t + 96

a) The polynomial is given as:

s = -16[tex]t^{2}[/tex] + 192t + 96

b) The height of the football when t = 2 seconds is;

s = -16(2) + 192(2) + 96

 = -32 + 384 + 96

 = -32 + 480

s = 448

The height of the football when t = 2 seconds is 448 feet.

ii. The football would not hit the ground after 2 seconds.

Step-by-step explanation:

Answer:

13.0 trillion pounds of carbon dioxide

Step-by-step explanation:

5.877 ÷ 0.4536 = 12.9563492063

rounded to 1 decimal place =

13.0 trillion pounds of carbon dioxide

The carbon dioxide released by United States is 12.9563 trillion pounds

In math, conversion is the process of changing the value of one form to another for example inches to millimeters, or liters to gallons.

Now it is given that,

Amount of carbon dioxide released by United States = 5.877 billion metric tons

It is also given that,

1 trillion pounds = 0.4536 billion metric tons

So, 1 billion metric tons = (1/0.4536) trillion pounds

Thus, 5.877 billion metric tons =  (5.877/0.4536) trillion pounds

⇒ 5.877 billion metric tons =  12.9563 trillion pounds

Thus, the carbon dioxide released by United States is 12.9563 trillion pounds

Answer: your Answer is $75 dollars.

Step-by-step explanation:

$25 + $50 = $75

Answer:

[tex]C = 50x + 25[/tex]

Step-by-step explanation:

The $50 charge can be interpreted as the slope, as it varies based on the amount of time the service takes. The $25 can be interpreted as the y-intercept, as you'll get charged $25 no matter how long the service takes. Thus, we can plug these values into the slope-intercept form equation.

Answer:

When y is 39 x is 3.

Step-by-step explanation:

Proportions!

x = 3

y = 13

We need to find our multiplier first. How did 13 turn into 39?

39/13 = 3

13 * 3 = 39

We multiplied by 3!

Now we multiply x by three to keep the propotion, proportional!

x= 3

(3) * 3 = 9

Now we make the proportion

3 : 39

When y is 39 x is 3.
