Answer:
putting value of m and n in the equation we get
10x5+ 4x2
= 50+8=58
You multiply 86 by 42.5 because each board is 42.5 and there are 86 boards.
Answer:
1. No
2. No
3. Yes
4. No
Step-by-step explanation:
The first one isn't proportional because it doesn't start at 0
The second one isn't proportional because there isn't a pattern between the coordinates
The 3rd one is a proportional relationship because it starts at 0 and there is an equal amount of space between each coordinate and there is evidentially a pattern.
Finally, the 4th one isn't proportional because the last coordinate doesn't correspond w/ the others
Plz mark me brainliest if correct :)
