Answer:
2m - 9
Step-by-step explanation:
To simplify this, we need to combine like terms. m + m = 2m and -4 - 5 = -9 so the simplified version would be 2m - 9.
If there are 3 red blocks for every 5 blocks
if we multiple both numbers by 12 to make every 60 blocks we get:
36 red blocks every 60 blocks
since you have 36 and you only need 32 then yes you will have enough
The answer is A) 12
