Answer:

Multiply the bottom one by -4

Step-by-step explanation:

to cancel in a system of equations, there must be a negative and a positive of both variables. - times - equals +, so multiply -x by -4 to get 4x, thus cancelling -4x with 4x.

A bag contains 6 red marbles and 2 white marbles. A marble is selected, kept out of the bag, and then another marble is selected
Finger [1]

Answer:

11/15

Step-by-step explanation:

There are 8 marbles total. If they are being selected from twice with one missing, we could add 8 and 8 - 1 together to get the denominator for the probability.

8 + (8 - 1) = 15

We have to assume the first marble taken was red, so we will have 6 plus 6 - 1 red marbles to choose from for our numerator.

6 + (6 - 1) = 11

The probability of consecutively selecting two red marbles is 11/15.
