Answer:
x is the price the helmets were sold at.
y is the business expenses.
r is the revenue.
500x - y = r
Step-by-step explanation:
500x - y = r
We multiply x, the price that the helmets were sold at. Then we subtract y, which is the business expenses. After this, we get r, our revenue.
(8c)^2+7c
(8c)^2=64c^2
so that..
64c^2+7c
factor out c
c(64c+7)
Answer:
Step-by-step explanation:
Expand:
Add 27 to both sides:
Add 12x to both sides:
Divide both sides by 4:
The cost to mail a 2-lb package is $7.
The cost to mail a 2-lb, 1 oz package is $7+$0.30(1).
That to mail a 2-lb, 2 oz package is $7+$0.30(2) = $7.60.
Following this pattern, the general formula is f(x) = $7 + $0.30x, where x represents the number of ounces OVER 2 lb.
These are vertical angles and vertical angles are congruent. So you set them equal to each other
5x+12=6x-10
-5x -5x
12= x-10
+10 +10
X=22
