Answer:
a-5b = 8
a = 8+5b ⇒ this is the solution
Answer cannot be specific.
Step-by-step explanation:
So we know that we need to figure out what A is. to be honest, A could be a lot of things when we don't know what b is. B could be 4, and that would make A=12. B could be 5, which would make A=17. We just don't quite know.
to find the adverage you have to add the times together then divide them by 2 so 2 + 1.5 = 3.5/2= 1.75
m = 65
