Answer:
Step-by-step explanation:
B/4=3.2
B=12.8
The square root of any number is the same as that number to the 1/2 power
root(b)=b^(1/2)
X would be 60, I don’t know an equation, but you can divide both sides by 4 and get 20% of c is 12, and then you can multiply both sides by 5 to get that 100% of x is 60, hope this helps!
50,000 because 5,000 multiply 10= 50,000
