Answer:

Step-by-step explanation:
x=unknown number




simplify the fraction so... -7/2
3. i=129; j=112
4.k=90;l=116;m=64;n=86
5.o=13;p=78;q=91
6.a=120;b=60;c=140
Can't see #7
You did 8 I believe
9.v=39;w=59;x=121
10.y=59;z=93
11.a=42;b=48;c=132
12.a=60;b=50;c=80;d=100
Indirect proportion: y = k/x.
Here, y = 2 / (3x); x is in the denominator of the fraction. Thus, this equation does represent indirect proportion, with k = (2/3).
2/3
y = -------
