joy added 26 new contacts to her phone list. She now has a total of 100 contacts. Let c represent how many contacts joy had on h
Nesterboy [21]

Answer: 26 + c = 100

Step-by-step explanation: To find what c equals, we must flip the solution around and subtract it. When we take 100 - 26, we get 74. Therefore, c = 74. I hope this helped! :)

PLEASE HELP! Find the height of a cylinder with a surface area of 108 pi square meters. The radius of the cylinder is twice the
Naily [24]
Assuming the cylinder is closed at both ends 
Surface area = 2 pi r^2 + 2 pi r h  = 108

now h = r/2 so we have:-

 2pi r^2 +  pi r^2= 108

 3 pi r^2   = 108
r^2 = 11.459
r =  3.385 
so the height h = 1.693 m to nearest thousandth

Answer:

35 <5m

35/5 < 5m/5

7 < m

m = 8,9,10,11,12,.......

a + 6 \geq 9

a + 6 - 6 \geq 9 -6

a  \geq 3

a = 3,4,5,6,7,......

8-g > 5

8 -g +g > 5 +g

8 > 5 +g

8 -5 > 5 -5 +g

3 > g

g =4,5,6,7,8.......
