(4m+9)−3(2m−5)= simplified in an expression

(4m + 9) - 3(-2m - 5)

(4m + 9) + 6m + 15

4m + 9 + 6m + 15

10m + 9 + 15

10m + 24

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
