Answer:
3 nickels and 5 quarters
Step-by-step explanation:
Let n = number of nickels
q = number of quarters
q = n+2
.25q + .05n = 1.40
Using the first equation and replacing q in the second equation
.25( n+2) + .05n = 1.40
Distribute
.25n+.50 +.05n = 1.40
Combine like terms
.30n +.5 = 1.40
Subtract .5 from each side
.3n +.5-.5 = 1.40-.4
.3n = .9
Divide by .3
.3n/.3 = .9/.3
n = 3
q = n+2
q=5

Answer:
-2
Step-by-step explanation:
f(x)=3x^2+5x-14
f(-3)=3(-3)^2+5(-3)-14
f(-3)=3(-3)(-3)-15-14
f(-3)=3(9)-29
f(-3)=27-29
f(-3)=-2
