To find the percent of a number, just turn the percentage into a decimal. To do that just go 2 decimal places to the left. For example, 25% becomes 0.25. Then, just multiply that decimal by the number you're finding the percentage of. That's it!

Ex. Find 50% of 10

50% becomes 0.5
0.5(10)= 5

50% of 10 is 5.

Need help remembering how to solve f(x)=5x2

nata0808 [166]

F(x)=5*2
the f(x) stands for a normal X like any other algebraic equation. so all it is, is 5 times 2, which is 10.
so,
f(x)=5*2
f(x)=10<span />
