#8. evaluation the expression when x=-1 and y = 3. 5x^-6y^-2/y

            5

      x^6 y^3

Step-by-step explanation:

If x=-1 and y = 3. what is the value of 5x^-6y^-2/y?

Important:  if you're working with negative exponents, please enclose them inside parentheses:

5x^(-6) y^(-2) / y^(1)                    1

First, the y terms become   = 1 / y^3  

                                              y^2 * y

                                                               5

Then  5x^(-6) y^(-2) / y^(1)  becomes (answer)

                                                             x^6 y^3

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
