Answer:
-6/5
Step-by-step explanation:
1/10x + 6 = 2/5x
6 = 2/5x - 1/10x
6 = 4/10x - 1/10x
6 = 3/10x
6 / (3/10) = x
6 * 10/3 = x
60/3 = x
20 = x <=== the gas tank can hold 20 gallons

Answer:
1/4 or 0.25
Step-by-step explanation:
- 3.2(4m + 10) – (-7.2m) = 37
- 12.8m+32+7.2m=37
- 20m= 37-32
- 20m=5
- m=5/20= 1/4 or 0.25
