Answer:
3 1/3 gallons per minute
Step-by-step explanation:
We can use ratio's to solve this problem. We will put gallons on top and time on the bottom
5/6 gallons x gallons
-------------------- = -------------
1/4 minute 1 minute
Using cross products
5/6*1 = 1/4 x
Multiply by 4 on each side
5/6 * 4 = 1/4 *4 x
20/6 = x
Dividing the top and bottom by 2
10/3 =x
Changing this back to a mixed number
3 goes into 10 3 times with 1 left over
3 1/3 gallons per minute
The answer to 5 is 20
the answer to 3 is 12
the answer to 4 is 16
Answer:
man's age = 54
daughter's age = 18
Step-by-step explanation:
x = man's age
y = daughters age
x = 3y
x - y = 36
substitute for x:
3y -y = 36
2y = 36
y = 18
x = 54
The numbers are equal. 25=25
