3) Valerie works at a local amusement park. She earns $9.80 per hour. She 20 points

NemiM [27]

<h3>Answer: Choice A</h3><h3>9.80h+10 = 88.40</h3>

===========================================================

Work Shown:

h = number of hours worked.
9.80h = amount of money earned after working h number of hours (ignoring the meal bonus).
9.80h+10 = total amount of money earned after adding on the meal bonus.
9.80h+10 = 88.40 is the equation we use since the total 9.80h+10 is the same as the total she earned 88.40 dollars.

--------------------

Extra info (optional section)

If you want to solve for h, then you could follow these steps.

9.80h+10 = 88.40

9.80h = 88.40-10 ... subtract 10 from both sides

9.80h = 78.40

h = 78.40/9.80 .... divide both sides by 9.80

h = 8

Valerie worked 8 hours on Friday.

As a check,

9.80h + 10 = 88.40

9.80*8 + 10 = 88.40

78.40 + 10 = 88.40

88.40 = 88.40

The answer is confirmed.

16+5x=8x-5 What would the variable be?

11111nata11111 [884]

16+5x =8x-5

Reorder the terms
16+5x = -5+8x
Solving for variable for x

Move all terms containing x to the left, all other terms to the right.
Add -8x to each side of the equation.
16+ -3x = -5 + 8x + -8x

Combine like terms: 5x + -8x=-3x
16+-3x = -5 + 8x + -8x

Combine like terms: 8x + -8x = 0
16+-3x = -5 + 0
16+ -3x = -5

Add -16 to each side of the equation
16+-16 + -3x = -5 + 16

Combine like terms: 16+ -16 = 0
0 + -3x =-5 + -16
-3x = -5 + -16

combine like terms: -5 + -16 = -21
-3x = -21
Divide each side by -3
x=7

erica [24]

If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
