20) -5(1 - 5x) +5(-8x - 2) = -4x – 8x

Alchen [17]

Answer:

x = -5

Step-by-step explanation:

-5(1 - 5x) +5(-8x - 2) = -4x – 8x

First lets simplify each side of the equation.

-5+25x-40x-10 = -4x-8x

Combine like terms

-15x-15=-12x

Add 15x to both sides (addition property of equality)

-15=3x

Divide each side by 3 (division property of equality)

x=-5

The answer is x = -5

A ball is dropped from a height of 14 ft. The elasticity of the ball is such that it always bounces up one-third the distance it

Korvikt [17]

Answer:

Hello,

742/27 (ft)

Step-by-step explanation:

$h_1=14\\\\h_2=\dfrac{14}{3} \\\\h_3=\dfrac{14}{9} \\\\h_4=\dfrac{14}{27} \\\\$

$d=14+2*\dfrac{14}{3} +2*\dfrac{14}{9} +2*\dfrac{14}{27} \\=14*(1+\dfrac{1}{3}+\dfrac{2}{9} +\dfrac{2}{27} )\\=14*\dfrac{53}{27} \\=\dfrac{742}{27} \\$
