Answer:
4.5 It doesn't come out evenly, but cross products do work.
Step-by-step explanation:
She is not correct.
50 * x = 3 * 75 Combine the right
50x = 225 Divide by 50
x = 225/50
x = 4.5
Simplify both sides then isolate the variable and it gives you y=3.6
If you're finding diameter or radius based on circumference, use the formula C = πd. You would divide the circumference by pi to get the diameter, then divide the diameter by 2 to get the radius.
If you're finding diameter or radius based on area, use the formula A = πr^2. You would divide the area by pi, then find the square root of that value which is the radius. Just multiply the radius by 2 to find diameter.
the answer to your question is x= -2
