830=52x
830/52=52x/52
Hence x = 15.96
Example:
<span>12 is 20% of 60. In order to get 12 percent of 60, all you need to do is to divide 12 with 60. To get the percent means to get the parts of 100. To get it in the form of percent, just multiply the quotient by 100. 12/60=.2 x 100 = 20% .</span>
It is A. 2n/15. You can think of n as the books
To solve for y, you need to isolate/get the variable "y" by itself in the inequality:
x + 8y < 16 Subtract x on both sides
x - x + 8y < 16 - x
8y < 16 - x Divide 8 on both sides to get "y" by itself
