Answer:
Let x = the number of quarters
Let y = the number of nickels
X + y = 62 x = 62 - y
.25x + .05y = 12.50 Multiply both sides of the equation by 100 to get rid of the decimal points.
25x + 5y = 1250
25(62-y) + 5y = 1250
1550 - 25y + 5y = 1250
-20y = -300
y = 15 nickels
x = 62 - y = 62 - 15
x = 47 quarters

Step-by-step explanation:
They are correct
18. S=r^2-t^2
S+t^2=r^2
r=sqrt(S+t^2)
20. Tan 18=x/12
x=12×Tan 18
x=3.899036355
x=3.90
I hope this helps.
