Answer:

The cost of 15 liters is $31.50

$2.10 per liter x 15 liters = $31.50

-3u-17=(u+8)<br> simplify
Ivanshal [37]

Answer:

-25/4 = u

Step-by-step explanation:

-3u-17=(u+8)

Add 3u to each side

-3u+3u-17=(u+3u+8)

-17 = 4u +8

Subtract 8 from each side

-17-8 = 4u+8-8

-25 = 4u

Divide by 4

-25/4 = 4u/4

-25/4 = u
