Answer:
7 $5 bills, 32 nickels
Step-by-step explanation:
Ok, so to solve this, we need to make two separate equations. If we say that x is the number of nickels, and y is the number of 5 dollar bills, adding up to $36.60, we can make the equations 0.05x + 5y = 36.60, and x + y = 39. Using substitution, we can say 0.05x + 5(39-x) = 36.60. This simplifies to 195-4.95x = 36.6. We can then say 158.4 = 4.95x, and x = 32. This means we have 32 nickels. As there are 39 total coins and bills, that means there are 7 $5 bills, and 32 nickels.
Answer:

Step-by-step explanation:
we know that
The perimeter P (in yards) of a soccer field is

where
L is the length in yards
W is the width in yards
Solve the equation for the width W
That means -----> isolate the variable W
Subtract 2L both sides

Divide by 2 both sides
