apply
a. 75/7 and (57)5
b. 5212 and ( 55 )
c. (1787)5 and 815/4
d. 6^2/7 and

for these, none of them are equivalent

(A. 75/7 and (57)5

B. 5212 and ( 55 )

c. (1787)5 and 815/4

D. 6^2/7 and ()?)

75/7 = 10.714

57*5 = 285

^ aren't equivalent

5212 and 55 are different numbers

1787*5 = 8935

815/4 = 203.75

^ aren't equivalent

6^2/7 = 36/7 = 5.143

I assume () means 0

^ aren't equivalent

$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)
