15= 3*5
14= 2*7
LCM(15,14)= 2*3*5*7= 210
15 and 14 go into 210 evenly~
Answer:
it should be 2 as your answer
Answer:
Its D, 5 4/9
Step-by-step explanation:
So you can turn them into improper feactipons if it’s hard at first (I can already do it without turning them into improper so it’s asker for me)
so 19/9-2/9+32/9
Now add them like you normally would since all the denominators are the same.
you’ll get 49/9
now just simplify that into a mixed mnumber
5 4/9
Ac - ab = 2
Factor out a
a(c-b) = 2
Then divide the expression by c-b to solve for a.
Do this on both sides.
a(c-b)/(c-b) = 2/(c-b)
a = 2/c-b
The solution is a = 2/c-b.
