Answer:

(v+8)8 is 8v + 64

Step-by-step explanation:

Because You have to multiply whats outside the parentheses by whats inside them. Since you cant multiply 8 times x because you don't know x value you just put 8x.

Your family of four has a 6 GB data limit each month. You use twice as much data as your sister, half as much data as your fathe

Let your monthly data use be represented by X
Then:
- Your sister's use is 1/2X (half of your usage)
- Your father's use is 2X (twice as much as you)
- Your mother's use is 4X (four times as much as you)

The total amount of GB use in your family can therefore be represented by
$\frac{1}{2} x + x + 2x + 4x = 7 \frac{1}{2} x$
This total GB use equals the limit of 6GB per month, so
$7 \frac{1}{2}x = 6$
Divide by 7.5
$x = 0.8$

Hence, you use 0.8 GB per month
- Your sister's use is 1/2 * 0.8 = 0.4GB (half of your usage)
- Your father's use is 2 * 0.8 = 1.6GB (twice as much as you)
- Your mother's use is 4 * 0.8 = 3.2GB (four times as much as you)
