21+(5f)=61
Subtract 21 to both sides of the equation
5f=40
Divide both sides by 5
f=8
The answer is 8
Answer:
x = 35 - y / 15
Step-by-step explanation:
3x + 1/5y = 7
3x + 1/5y - 1/5y = 7 - 1/5y
3x = 7 - 1/5y
3x/3 = 7/3 - 1/5y / 3
x = 35 - y / 15
The answer is 20 minutes. An hr has 60 minutes therefore when divided by 6, 2/6 is equal to 20 minutes
