Answer:
A 5
Step-by-step explanation:
Parts on the left have the same ratio as parts on the right.
... x/(x+5) = (x -2)/(x +1)
Multiplying by (x+5)(x+1), we get
... x(x +1) = (x -2)(x +5)
... x² +x = x² +3x -10 . . . . eliminate parentheses
... 0 = 2x -10 . . . . . . . . . . subtract x²+x
... 0 = x -5 . . . . . . . . . . . . divide by 2
... 5 = x . . . . . . . . . . . . . . . add 5
6/10 + 7/12 = 142/120 = 71/60 = 1.18 (One whole number, and 11/60)
I think 18?
tbh dont listen to that, its just a guess
1) 3/40 2) 32 3) 1 4) 1/42 i think 10)3/1/2 i think hope its right
