These are the first sentences in the short story, "the gift of the magi," by o. henry:
"one dollar and eighty-seven cents. that was all. and sixty cents of it was in pennies."
a. simplify the equation that represents the value of the coins. make it an equation that expresses the value of quarters, dimes, and nickels.
b. is it possible to have exactly 60 pennies in $1.87? explain.
.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
