Lets say i need to find 10 percent of 25 percent? thanks also i have another question i dont get.
If X=-2 and y=5, what is the value of the expression 2xcubed -3xyHow do you calculate percentage of a percentage?
It's always the same no matter what; set up your ratios first. 10 over 25 = x over 100. You get 2.5
Just 'plug in' the variables to the equation. ( I'll use an * for the multiplication symbol)
2 * -2 cubed -3 * -2 * 5= 14
Simplify.
-16 + 30= 14
