y = x - 4
Step-by-step explanation:
The answer would be c hope this helps
For x=3
3 + 3·3 + 5 = 17 ≠ 33
For x=5
5 +3·5 + 5 = 25 ≠ 33
For x=7
7 + 3·7 + 5 = 33 . . . . . this is the solution
For x=9
9 + 3·9 + 5 = 41 ≠ 33
Answer:
x = 9.5y
Step-by-step explanation:
7 lawns = $66.50
1 lawn = $66.50 ÷ 7
= $9.50
You now know that for one lawn mowed, the amount of money earned is $9.50. Thus:
1x = 9.5y
x = 9.5y
8.9% is equal to 0.089 because a percent is over a 100. So, you can just multiply the ROI by the investment to get:
Your answer is:
$712.
