c is greater than 21-13
c is greater than 7
Step-by-step explanation:
V=hπr^2
V=(2k+1)π(3k)^2
V=π(2k+1)(9k^2)
V=π(18k^3+9k^2)
V=18πk^3+9πk^2
Answer:
$2
Step-by-step explanation:
x = daylily
y = geranium
1x + 5y = 22
13x + 1y = 30
Multiply second equation by 5 and subtract the two equations.
1x + 5y = 22
- (65x + 5y = 150)
-64x = -128
x = 2
So one daylily costs 2 dollars
