Answer:
The last choice: 25. 12 / pi
Explanation:
The relationship b
It’s should be -30 instead of 30 so the answer would be y= -3
N=number of nickles
d=number of dimes
q=number of quarters
use cents for everything
total value=585
5n+10d+25q=585
divide everybody by 5 to simplify
n+2d+5q=117
we have
nicles are 5 more than quarters
n=5+q
4 times as many dimes as quarters
d=4 times q
d=4q
sub those in
5+q+2(4q)+5q=117
5+6q+8q=117
5+14q=117
minus 5
14q=112
q=8
sub back
n=5+q
n=5+8
n=13
d=4q
d=4(8)
d=32
13 nickles
32 dimes
8 quarters
divide both sides by 22
Answer:
D
Step-by-step explanation:
D. 360 cm squared
Explanation:
Multiply each faces edges.
18x7(WxL)
3x6(HxW)
3x18(HxL)
multiply each equations answer by 2, because the opposite face is the same.
108x2=216
18x2=36
54x2=108
add these together to get 360 cm squared.
