Answer: 117.5
Explanation: Assuming that after 10 years the lawn mower would have a value of 0. We can evenly divide $470 by the amount of years.
$750/10 = $75
We would then multiply 75*7.5 years to then realize the value lost over that amount of time would be $352.5, subtracting that from the original value of $470 would then be 117.5
Answer:
37 cubic cm should be the answer sorry if I am wrong
-4 x 9 - (-10)
= - 45 + 10
= - (45 - 10)
= - 35
Rule: Negative times positive is negative; Negative times negative is positive
X= 9/2, 15/2
decimal form: 4.5,-7.5
mixed number form: 4 1/2, -7 1/2
