Answer:
93.1
24.83
24.13
2755
12.75
0.151
Step-by-step explanation:
Given :
21.1 + 45.99 + 26.0 = 93.09
15.55 + 21.61 - 12.333 = 24.827
14 + 0.8 + 9.33 = 24.13
14.5 * 190 = 2755
5.1 * 2.5 = 12.75
0.15 ÷ 0.991 = 0.151

Answer:
- n = 5q; 25q+5n = 200
- (n, q) = (20, 4)
- Margie has 20 nickels and 4 quarters
Step-by-step explanation:
a) Using the defined variables, we can translate the problem statements to equations:
- n = 5q . . . . Margie has 5 times as many nickels as quarters
- 25q + 5n = 200 . . . . the total value of Margie's coins is 200 cents
__
b) Substituting for n, we have ...
25q +5(5q) = 200
50q = 200 . . . . . . . collect terms
q = 200/50 = 4 . . . divide by the coefficient of q
n = 5·4 = 20
The solution is (n, q) = (20, 4).
__
c) Since n represents the number of nickels Margie has, n=20 means Margie has 20 nickels. Similarly, q=4 means Margie has 4 quarters.
