Answer: 54 mph
Step-by-step explanation:
d-the distance
s+9 - the speed to the conference
d=6*(s+9)
s- is the speed on the way back home
d=7*s
so 6*(s+9)=7*s
6s+54=7s
-6s -6s
54= 7s-6s
s=54 mph

Answer:
what is the 2nd problem????
Step-by-step explanation:
So, to find the find the amount of fencing required, or the circumference of the gardening, pot...
Area = pi * r^2
125 square feet = pi *r^2
125/ pi = r^2
39.79 = r^2
root square of 39.79 = r
6.31 = r
To find the circumference, the formula is: pi * D (or Pi * r * 2)
therefore,
C = pi * 6.31 *2
C = 39.65 feet
therefore, 39.65 feet of fencing is needed.
hope this helps
