Answer:

<h2>B) $10.00</h2>

Step-by-step explanation:

x - Earl's earnings per hour

The equation:

18x = 15(x + 2)         <em>use the distributive property</em>

18x = (15)(x) + (15)(2)

18x = 15x + 30        <em>subtract 15x from both sides</em>

18x - 15x = 15x - 15x + 30

3x = 30        <em>divide both sides by 3</em>

3x : 3 = 30 : 3

x = 10

The perimeter of a stop sign has a perimeter of 16x2 - 80x. What is the length of one side?
uranmaximum [27]
Since a stop sign is an octagon it has eight sides.  So the perimeter will be:

p=8x,  p=perimeter and x=side length.  We are told that the perimeter is equal to:

16x^2-80x so we can say:

16x^2-80x=8x subtract 8x from both sides

16x^2-88x=0  factor out 8x

8x(2x-11), since we know x>0

x=11/2

x=5.5 units
