All you have to do is move the denominator on the other side, by multiplying.
a-10
------- = -9
20
multiply 20 x -9
= -180
then it becomes a-10=-180
+10 +10
a=-170
Answer:
80 feet
Step-by-step explanation:
c=d
Substitute 250 in for circumference
250=d
Divide by or 3.14
d=79.617...
So, the diameter is approximately 80 feet
Hope this helps! :)
First move the terms to get
6m-m=13+2
Then collect the like terms and calculate the sum, 5m=15
Divide both sides by 5
And you get m=3
Pi*3^2= 9pi
pi*6=6pi
6pi*17= 102pi
102pi+9pi= 111pi in. squared
pi*6^2=36pi
pi*12=12pi
36pi+12pi*x=111pi
12pi*x=75pi
x=6.25pi
x=Height btw
