Alexandra has 36 coins valued at $6.00. She has only nickels and quarters. Which equation can be used to solve for the number of
nickels, n?
0.05n + 0.25(36 – n) = 6
0.05n + 0.25(36 – n) = 36
n + 0.05 = 0.05n
n + (36 – n) = 36

Answer:
Let n be the number of nickels and q be the number of quarters, then
n + q = 36 . . . (1)
0.05n + 0.25q = 6 . . . (2)
From (1): q = 36 - n . . . (3)
Putting (3) into (2) gives:
0.05n + 0.25(36 - n) = 6

4x+11 is the answer.
Step-by-step explanation:
( 4*2-x+3)-(3*2-5x-6)
=(8-x+3)-(6-5x-6)
=(11-x)-(0-5x)
=(11-x)-(-5x)
=11-x+5x
=11+4x
= 4x+11
