With shells, the volume is given by
Answer:

Step-by-step explanation:
The given inequality is
x+ (7 + 2x) <-3x
Expand parenthesis to get
x+ 7 + 2x <-3x
Group similar terms
x+ 2x +3x<-7
Combine similar terms
6x<-7
Divide both sides by 6

Rewrite as improper fraction

10d+ 25q+5n= 805
D= n+8
Q= n+ 5
10d+ 25q+5n= 805
10(n+8)+25(n+5)+5n=805
10n+80+25n+125+5n=805
40n+205=805
40n=805-205
40n= 600
N=600/40
N= 15
D= n+8
D= 15+8
D= 23
Q=n+5
Q=15+5
Q=20
So 15 nickels ,23 dimes and 20quarters .
To check
15(0.05)= $0.75
23(0.10)=$2.30
20(0.25)=$5.00
Add it
5.00+2.30+0.75=8.05
7.30+.75=8.05
8.05=8.05
