Find the value of x if g(x) = - 18 for g(x) = 2x - 8
nalin [4]

Hi there!

\large\boxed{x = -5}

Find the value of 8 by substituting in -18 for g(x):

-18 = 2x - 8

Add 8 to both sides:

-10 = 2x

Divide both sides by 2:

-10/2 = 2x/2

x = -5

Middle school problem attached :D
suter [353]

Answer: $638.40

Step-by-step explanation:

45% converted to a decimal is 0.45

0.45 of $1200 = 0.45* $1200 (of in this case means multiply)

0.45 * $1200= $440

Because they said 11% of remaining salary, we have to do:

$1200-$440=$760

Now 11% converted to a decimal is 0.11

5% converted to a decimal is 0.05

So 0.11+0.05

0.11+0.05= 0.16

Now 0.16 *$760=$121.60

Now we find the remaining amount so we subtract: $760-$121.60= $638.40

So our answer is $638.40 left
