Z

Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30
Part B;
Z

z=

Where x is a constant of proportionality,
when x=3, z=2
2=

a=3*2
a=6
When x is 13,
Z=
First, let's look at the formulas for the area of square and area of the rectangle.


And what this exercise states is that the areas are the same. So:

Now put in the data.

Solve for
:

The side of the square garden plot is 4 meters.
Hope this helps.

Answer:
c
Step-by-step explanation:
So for eliminating, you only solve for one variable first.
I solved for y, so I multiplied by -4 to eliminate the x.
Then I got y= -1
I then substituted that to one of the equations to get x.
