First of all, this is an expression, since it is not set equal to anything; therefore, you can't solve it.
However, you can simplify it.
The simplified expression would be
x+5y+10
Hope this helps!
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:
Has to be the first one....
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First you have to get it to y intercept for which is y=mx+b so you would subtract 7x and bring it to the other side so now u have -3y=7x+21 next u would divide -3 to get y alone so u would have now is y= -7/3x+ 7 then when u graph it the y intercept is 7 so u graph 7 on the y axis and the slope is -7/3 so u would go down 7 and over 3
