You have to find out what X is which you need to do -2 - (-11) and then do -9 - (-11) after that do you-2 x -2 and get -4

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

1/2(8x - 4) = 2x

<u>Step 2: Solve for </u><em><u>x</u></em>

[Distributive Property] Distribute 1/2: 4x - 2 = 2x
[Subtraction Property of Equality] Subtract 2x on both sides: 2x - 2 = 0
[Addition Property of Equality] Add 2 on both sides: 2x = 2
[Division Property of Equality] Divide 2 on both sides: x = 1

Answer:

Mai lives 384 miles away from the mountains

Step-by-step explanation:

Let d represent distance between Mai's house and mountains and r represent Mai's rate while going to mountains.

We have been given that there was heavy traffic on the way there, and the trip to mountains took 8 hours.

$\text{Distance}}=\text{Time}\times \text{Speed}$

$d=8r...(1)$

We are also told that when Mai drove home, there was no traffic and the trip only took 6 hours. Her average rate was 16 miles per hour faster on the trip home.

$d=6(r+16)...(2)$

Upon equating equation (1) and equation (2), we will get:

$8r=6(r+16)$

$8r=6r+96$

$8r-6r=6r-6r+96$

$2r=96$

$\frac{2r}{2}=\frac{96}{2}$

$r=48$

Upon substituting $r=48$ in equation (1), we will get:

$d=8r\Rightarrow 8(48)=384$

Therefore, Mai lives 384 miles away from the mountains.
