For a given input value x, the function h outputs a value y to satisfy the following equation 6x+y=4x+11y. Write a formula for h
Tanzania [10]

Answer: h(x) = \frac{1}{5}x

<u>Step-by-step explanation:</u>

6x + y = 4x + 11y

<u>      -y </u>    <u>        -y  </u>

6x       = 4x + 10y

<u>-4x   </u>      <u>-4x         </u>

2x       =         10y

<u>÷10    </u>     <u>       ÷10 </u>

\frac{1}{5}x    =            y

Since "y" represents h(x), then h(x) = \frac{1}{5}x

Jlenok [28]

Answer:

Each boy recieved $25.25 each

Step-by-step explanation:

First, you add up all the money the 3 boys spent.

15+15+15=45

Then you add the sum of the equation to the amount all the boys had afterward.

45+30.75=75.75

Finally, you divide that product to 3 boys.

75.75/3=25.25

Therfore the answer is $25.25 each.
