Answer:
idk I need the answer too
Step-by-step explanation:
:P
Let the original volume be pi *r^2* h where r = radius and h = height.
The new volume will be pi *(2/5 r)^2 * 4h = pi*4/25 r^2 4h
pi*4/25r^2 * 4h / pi r^2 h = 4/25 * 4 = 16/25
The volume has been reduced by factor of 16/25.
Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:
Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12

The first one is 2/1 the second one is 1/1
Answer:
2(x+5)
Step-by-step explanation:
7x+1-(5x-9)
=7x+1-5x+9
=2x+10
=2(x+5)
