My work and the answer is shown up in the picture.
I used the substitution method to check my answers by using x and y into the two equations.
100%/x%=12/15
<span>(100/x)*x=(12/15)*x - </span>we multiply both sides of the equation by x
<span>100=0.8*x - </span>we divide both sides of the equation by (0.8) to get x
<span>100/0.8=x </span>
<span>125=x </span>
<span>x=125
so 125%</span>
Step-by-step explanation:
Area of rectangle= l×b
= 4cm×6cm
= 24cm²
Area of circle. = πr²
radius of circle = diameter÷2=6÷2=3cm
Area of circle. = 3.14×3²=3.14×9
Area of circle. = 28.26cm²

Area of........... = 28.26cm²+24cm²
= 52.26cm²
