Olenka [21]

Answer:

4x + 5 = 101

Step-by-step explanation:

<u>Step 1: Determine how much money both have</u>

Aylen: x

Rich: 5 + 3x

<u>Step 2: Write an equation and solve</u>

Aylen + Rich = 101

x + 5 + 3x = 101

<u>Step 3: Solve the equation</u>

x + 5 + 3x = 101

4x = 96

x = 24

Review the bar graph below:
Scrat [10]

Answer:

B. 12.5%

Step-by-step explanation:

Add all the hours together to get 20. We make the assumption that 20 is 100% since it is our output value. We next represent the value we seek with x. From step 1, it follows that 100%=20. In the same vein, x%=2.5.This gives us a pair of simple equations:

100%=20(1)

x%=2.5(2)

By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS  (left hand side) of both equations have the same unit (%); we have

\frac{100}{x}=\frac{20}{2.5}

Taking the inverse (or reciprocal) of both sides gives us this:

\frac{x}{100} =\frac{2.5}{20}

>> x=12.5\%  

Therefore, 2.5 is 12.5% of 20.
