<u>Move 2πr² to the left side of the equation</u>
That's
2πrh = S - 2πr²
<u>Divide both sides by 2πr to make h stand alone</u>
That's

Answer:
x=4
Step-by-step explanation:
5-3(2x-7)=5-6x+21=-6x+26
--------------------------------------
12-5(x-2)=12-5x+10=-5x+22
--------------------------------------
-6x+26=-5x+22
-6x-(-5x)=22-26
-6x+5x=-4
-x=-4
x=4
Answer:
Part A:
c = .86*p
c =1.72 for 2 lbs
Part B:
c =.81p
Step-by-step explanation:
Part A:
Total cost = cost per pound * number of pounds
c = .86*p
Let p = 2
c = .86*2
c =1.72
Part B:
Total cost = cost per pound * number of pounds
c = .(.86-.05)*p
c =.81p
