Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowa

Fudgin [204]

7.50h + 0.20s + 40

variable : a letter subbed in for an unknown number : s and h
coefficient : the number multiplied by the variable : 7.50 and 0.20
constant : just a lone number, no variable attached : 40

Corrine works for 25 hrs and sells 300......h = 25, s = 300
7.50h + 0.20s + 40
7.50(25) + 0.20(300) + 40 =
187.50 + 60 + 40 =
287.50 <===

if she gets a raise and earns 9 per hr...
the coefficient would change from 7.50 per hr to 9.00 per hr. because her pay rate has changed.
the new equation would then be : 9h + 0.20s + 40

Complete the steps in solving 4/9=x/36

Whitepunk [10]

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

Cross multiply

(4/9)(9)(36) = (x/36)(36)(9)

(4)(36) = (x)(9)

Simplify

144 = 9x

Isolate the x. Divide 9 from both sides

144/9 = 9x/9

x = 144/9

x = 16

16 is your answer

hope this helps

bulgar [2K]

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

$\frac{y}{x}$ = m
