We know that
A relationship between two variables, x, and y,<span> is proportional if it can be expressed in the form y/x=k or y=kx</span>
in this problem
k=2
then
y=2x
therefore
the answer is the option
y=2x
Hey there
Lets solve this question together,
Convert <span>76.8%</span><span> to a decimal.
</span>
Multiply 0.768<span> by </span>x<span> to get </span><span>0.768x</span><span>.
</span>
Multiply<span> each </span>term<span> by </span><span>1 / 0.768</span><span> and simplify.
</span>
Cancel the common factor of 0.768.
Divide 40.32<span> by </span>0.768<span> to get </span><span>52.5
</span>

24 x 30 = 720 sq. ft
36 x 108= 3888 sq. inches
3888 inches divided by 12 inches= 324 ft.
720 ft - 324 ft. = 396 ft is the yard only without the garden
