yes thats involved, but first you have to replace q and n with the answer choices
q is quarters and n is nickels

A is 75 quarters; 75 nickels
so replace q and n in the equation
75(0.25) + 75(0.5) = 26.70

Answer 39

Faith mixes 14 liters of 12% acid solution with a 30% acid solution which results in an 18% acid solution.

If x represents the number of liters of 30% acid solution used, which equation can be used to find the number of liters of 30% acid solution in the mixture?

(Points : 1)
1.68 + 0.3x = 0.18(x + 14)
2.52 + 0.3x = 0.12(x + 14)
4.2 + 0.18x = 0.3(x + 14)
1.68 + 0.18x = 0.3(x + 14)

Answer 40

I think A

Answer 41

yes you are correct

Answer 42

Fiona has a jar filled with 150 coins made up of quarters and nickels. The total value of the coins is $25.10.

If x represents the number of quarters in the jar, which equation can be used to find the number of quarters?
0.25x + 0.05(x – 150) = 25.10 (Incorrect)
0.05x + 0.25(150 – x) = 25.10 (Incorrect)
0.05x + 0.25(x – 150) = 25.10 (Incorrect)
0.25x + 0.05(150 – x) = 25.10 (Correct)
