Answer:
135 pennies
Step-by-step explanation:
x= pennies in the door at the start
x-1/3x-1/3(x-1/3x)-1/3(x-1/3x-1/3(x-1/3x))=40
x = 135
Proof:
135-45-20 =40
135-45=90
90=30=60
60-20=40
Is means equals
sum means to add
product means to multiple
quotient means to divide
this is a division because it is asking for cost per gallon and they give you both the total gallons purchased and the total cost
28.49 divided by 7.5 = 3.798 or 3.80 rounded

Answer: B. There is no solution to the equation.
Answer:
The slope is 6.
Step-by-step explanation:
For this, you will want to use the slope formula.
m = y2 - y1 / x2 - x1
m = 14 - 2 / 19 - 17
m = 12 / 2
m = 6
Answer:
Yes
Step-by-step explanation:
Substituting in x = -7, we get y = 6(-7) = -42, which is the same as the y coordinate of the given point.
