Step-by-step explanation:
tried substitution and elimination method but got different answers to I graphed these equations and found the point of intersection
5/3x + 25/8y = 31.25
29/12x + 9/16y = 15.15
point of intersection (4.5, 7.6)
I=Lmv
m=i/Lv
Just divide the other two
Isolating the variable 'a' in the expression, we have:

So the correct option is B.
A is the right one:
a. 3:4=9:12
3×3:4×3=9:12
