Ответ:
1. You have the following information:
- April put gasoline in 4 of her 5 gallons cans.
- She put gasoline in 6 of her 2 gallons cans.
2. Let's call "x" to the number of gallons of gas that she bought. Therefore, you have:
x=(4x5 gallons)+(6x2 gallons)
x=20 gallons+12 gallons
3. Finally, the result is:
x=32 gallons
How many gallons of gas did she buy?
The answer is: 32 gallons

Step-by-step explanation:
Perimeter = 2 [Length+Breadth] PR = 2 [L+B]
Given : L = 3B - 5 , PR = 70
PR = 2 [L+B]
PR = 2 [(3B - 5) + B]
70 = 2 [4B - 5]
70 = 8B - 10
80 = 8B
B = 10
