Answer:

see below

Step-by-step explanation:

│ x + 8│- 5= 2

Add 5 to each side

│ x + 8│- 5+5= 2+5

│ x + 8│= 7

The absolute value has two solutions, a positive and a negative

x+8 = 7 x+8=-7

Subtract 8 from all sides

x+8-8 = 7-8 x+8-8 = -7-8

x = -1 x = -15

How far will a wheel with a radius of 3.5 feet travel in 500 revolutions? (Use 22/7 for tt)

storchak [24]

<span>C = 2πr
C = 2(2/7)(3.5)
= 22
Distance traveled by the wheel in one revolution is 22 feet.
Distance traveled in 500 revolutions will be: 500 x 22 = 11,000 feet.</span>

Simplify:- ~~~~~~~

Alchen [17]

$\sf \dashrightarrow \: - \frac{2}{5} - ( - \frac{3}{10} ) - ( - \frac{4}{7} )$

When there is a - in front of an expression in parentheses, change the sign of each term in the expression to +

$\sf \dashrightarrow \: - \frac{2}{5} + \frac{3}{10} + \frac{4}{7}$

Calculate the LCM of denominators

$\sf\frac{ - 28 + 21 + 40}{70}$

Calculate the difference

$\bf \underline{ \underline \frac{33}{70} }$
