#8: $900. (I found this answer by multiplying 3000 and 0.3 by the way)
#9: 160 miles. I found this answer by multiplying 80 by two, since two halves/50% make a whole or 100%.
Do (7x3)=21x7=147 so that’s how you do it hope it helps
In this case you would set it up as

(180 represents the degree of the triangle)
Add up like terms

Subtract 130 to the other side (180-130)

Divide 10 to the other side ( 50/10)
.

Hope this was clear :)
Answer:
D: (5 * 3)^3
D: 125 x 27
Step-by-step explanation:
Find the price for each apple by dividing the price over the number of apples. At Quixk Market, each apple costs 1.05/3 or $.35 per apple.
At Stop and Save, you can buy one apple for 2.45/5 or $.49.
The Quick Market is a better buy because It has $.15 less for each apple.
Hope this helps.
