Ms. Kline is baking cookies. She wants to bake cookies for eight friends. Each friend needs to receive at least ten cookies. The recipe she is using makes 55 cookies in one batch. 1. How many batches of cookies does she need to bake to give each person ten cookies?
2. How many cookies will be left over?

1. 2 batches

2. 30 cookies

Step-by-step explanation:

8*10=80 so you need to make 80 cookies...

55+55=110

110-80=30

Step-by-step explanation: She need to make 2 batches of cookies. She will have 110 cookies in total to give the eight friends 10 cookies each.

There will be 30 cookies left

examine the two-step equation.

−

+  

x

= 2

which property of operations allows you to add the same constant term to both sides?

multiplication property of equality

division property of equality

addition property of equality

subtraction property of equality

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
