Answer:
k = 3.70
Step-by-step explanation:
Eliminate parentheses, then subtract the constant term on the left
8.5 +4 -10k = -24.5
-10k = -37 . . . . . . . . . . 12.5 subtracted from both sides
k = 3.70 . . . . . . . . . . . both sides divided by -10 (no rounding required)
First of all (3x + 50) is equal to (6x - 10)
so (3x + 50) = (6x - 10)
3x + 50 = 6x - 10
60 = 3x
20 = x
There ya go!
2x + 3y = -1.....(5)
5x + 8y = 0.....(-2)
-----------------------
10x + 15y = -5
-10x - 16y = 0
-----------------------add
-y = -5
y = 5 <=====this is where Janet messed up
2x + 3y = -1
2x + 3(5) = -1
2x + 15 = -1
2x = -1-15
2x = -16
x = -16/2
x = - 8
solution is : (-8,5)
Volume of the Cone = (π*r^2*h)/3
CONE has 4 letters in it. CYLINDER has 8 letters in it. So Cone volume < Cylinder volume..
