Hello,
The answer is "x=94.5".
Reason:
54/x=100/175
(54/x)*x=(100/175)*x - we multiply both sides of the equation by x
54=0.57142857142857*x - we divide both sides of the equation by (0.57142857142857) to get x
54/0.57142857142857=x
94.5=x
x=94.5
If you need anymore help feel free to ask me!
Hope this helps!
