Answer:
e = 300 + .0275c
Step-by-step explanation:
So the earnings = e
Then she earns $300 and a bonus for cosmetics : 2.75%c which is equal to 0.0275 c or .0275c the c for cosmetics.
Thus the answer becomes :
e = $300 + .0275c

To get the answer, you have to isolate x. The first step to do so is to get the x's together, and the rest on the other side. You add 2 to both sides to get rid of the -2 on the left side, and add x to both sides to get rid of the -x on the right side so you have:
6x=-18
Your final step to isolating x is to divide both sides by 6 so you get:
x=-3
Answer:
The three consecutive odd integers are: -11, -13 and -15.
Step-by-step explanation:
Let the smallest number be represented by x. then the three consecutive odd integers are: x, (x + 2) and (x = 4).
The sum of the smallest number and twice the larges number = x + 2(x + 4)
Fifteen more than four times the middle number = 4(x + 2) + 15
So that;
x + 2(x + 4) = 4(x + 2) + 15
x + 2x + 8 = 4x + 8 + 15
3x + 8 = 4x + 23
3x - 4x = 23 - 8
-1x = 15
⇒ x = -15
(x + 2) = (-15 + 2) = -13
(x + 4) = (-15 + 4) = -11
The three consecutive odd integers are: -11, -13 and -15.
