Step-by-step explanation:
GIven
x: number of nickels
y: number of quarters
A nickel = $0.05
A quarter = $0.25
then we have the system of equations
0.05*x + 0.25*y = 11.90
x + y = 74
Which can be solved applying any of known methods. Then, the solution is
x = 33
y = 41
hope this was helpful.

Answer:
1 cm to 7.5 m
Step-by-step explanation:
A drawing scale is a ratio of two numbers.
The given scale, 4 cm to 30 m, can be written as a ratio in the form of a fraction,
(4 cm)/(30 m)
Since it can be written as a fraction, it can also be reduced like a fraction.
The problem wants the number of cm to be 1 cm. We have 4 cm.
Divide the numerator and denominator by 4.
(1 cm)/(7.5 m)
Now write it in the format the problem asks.
1 cm to 7.5 m
