What is the value of x in the equation ?2.5(6x-4)=10 4(1.5 0.5x)

MA_775_DIABLO [31]

2.5(6x−4)=(10)(4)(1.5)(0.5)x

(2.5)(6x)+(2.5)(−4)=(10)(4)(1.5)(0.5)x(Distribute)15x+−10=30x
15x−10=30x

15x−10−30x=30x−30x−15x−10=0

−15x−10+10=0+10−15x=10
−15x−15=10−15x=−23
Answer:x=−23

N76 [4]

Volume of Cylinder = $\pi r^{2}h$
Based on what we're told:
r (radius) = $\frac{s}{2}$
h (height) = $s$
So:
Volume of cylinder = $\pi (\frac{s}{2})^{2}(s)$
= $\frac{1}{2}s^{3} \pi$

A pencil and a ruler cost 2.50 together. The ruler costs $1.00 more than the pencil. How much is the pencil

Alenkasestr [34]

P + r = 2.50
r = p + 1

p + p + 1 = 2.50
2p + 1 = 2.50
2p = 2.50 - 1
2p = 1.50
p = 1.50/2
p = 0.75 <=== pencil cost 75 cents

r = p + 1
r = 0.75 + 1
r = 1.75 .....ruler cost 1.75
