<em>Equation:</em>
9(a+2)=189
<em>Solve the equation:</em>
9a+18=189
9a=189-18
9a=171
a=171/9
a=19
<em>Check the solution:</em>
Let a=19
9(19+2)=189
171+18=189
189=189
Therefore, the equation is 9(a+2)=189 and a is 19.
Answer:
Step-by-step explanation:
Circumference formula:
1/the rate of leakage per hour
This will give you the time it takes for 1 gallon to leak out in hours.
For example, if something is leaking at the rate of 12 gallons per hour, it will take 1/12 of an hour for 1 gallon to leak out. ( or 5 min)
