Answer:
hotdogs 3.45
rolls 2.60
Step-by-step explanation:
6h + 8r = 41.5
r=h-.85
6h + 8(h-.85)=41.5
6h + 8h - 6.8 = 41.5
14h = 41.5 + 6.8
14h = 48.3
h=48.3/14
h=3.45
r=3.45-.85=2.6
Answer:
x = 5
y = 6
Step-by-step explanation:
-3x + 2y = -3
-x - y = -11 (Multiply everything by 2)
-3x + 2y = -3
-2x - 2y = -22
-5x = -25
x = 5
-x - y = -11
-5 - y = -11
-y = -11 + 5
-y = -6
y = 6
So this is the volume of a cylinder:
V=hπr^2 to solve for h, divide both sides of the equation by πr^2
h=V/(πr^2)
