Answer:
![\boxed{\sf n = 2m - 8}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Csf%20n%20%3D%202m%20-%208%7D%20)
Step-by-step explanation:
Solve for n:
⇒2m - n = 8
Subtract 2 m from both sides:
⇒2m - 2m - n = 8 - 2m
2m - 2m = 0:
⇒-n = 8 - 2 m
Multiply both sides by -1:
⇒-n × (-1) = (8 - 2m) × (-1)
⇒n = 2m - 8
Answer:
36 nickels and 20 quarters
Step-by-step explanation:
36x5= 180
25x20=500
500+180=680=6.80
1/5.
If 4 pieces of gum are each divided into 5 parts, that will mean there will be 20 smaller parts (5*4=20).
Each person will get one part of each piece of gum. If there are 4 pieces of gum originally, this means each person gets 4 small pieces of gum
If each person gets 4 small pieces of gum and there are 20 small pieces altogether, that makes the fraction 4/20
Since 4 and 20 are both divisible by 4, that makes the simplified answer 1/5.
Does this have a graph???
