Answer:
E
Step-by-step explanation:
2c + 7 > 0
2c > -7
c > -7/2
If c < -7/2
-2c -7 -3 > 4
-2c > 14
c < -7
if c > -7/2
2c + 7 -3 >4
2c >0
c >0
D=2n
.05n+.1d=3.5
I multiplied the nickels and dimes by these values because that is their actual monetary value
.05n=3.5-.1d
multiply everything by 20
n=70-2d
d/2=70-2d
.5d+2d=70
2.5d=70
d=28
n=14
so there are <u>28 dimes and 14 nickels
</u>checking this answer
28 dimes = $2.8
14 nickels = .70
2.8+.7=3.5
