Answer:
Step-by-step explanation:
y = total cost of gas
x = gallons of gas
(a)
y = 1.60x
(b)
y = 1.60x
32.00 = 1.60x
32.00 / 1.60 = 1.60x / 1.60
32.00 / 1.60 = x
20 = x
x = 20
Trevor bought 20 gallons of gas.
Answer:
do you have another picture it's very blurry
Step 1 : Simplify both sides
-5(6a+21)=-15
(-5)(6a)+(-5)(21)=-15
-30a-105=-15
Step 2 : Add 105 to both sides
-30a-105+105=-15+105
-30a=90
Step 3 : Divide both sides by -30
-30a=90
—————
-30 -30
a = -3
Use distributed
2x-1=15-6x
2x+6x=15+1
8x=16
X=16/8
X=2
