Answer:

20

Step-by-step explanation:

3x + 4x - 15

3(5)+4(5) - 15

15 + 20 - 15

You can add the oposites

15 + (-15)

= 0

And then you have 20 left. Or add 15 + 20 = 35 then subtract 15 (which equals 20)

Hope this helps!

Delicious77 [7]

Answer:

(- 9, 2)

Step-by-step explanation:

Substitute x = - 9 into the equation and solve for x

4(- 9) + y = - 34

- 36 + y = - 34 ( add 36 to both sides )

y = 2

Thus (- 9, 2) satisfies the equation

A student pulls out a marble from a pag containing blue, green, and red marbles. He records the color and places it back into th
Mashutka [201]

Answer:

Answer is B - 290.

Step-by-step explanation:

The idea here is that we're assuming the frequency each colour is drawn is a reflection of the proportion of marbles in the bag that are that colour. The more of a particular colour you have, the more likely you are to draw it, and vice versa.

Therefore we can assume the proportion of blue, gree, and red marbles is 13%, 29%, and 58% respectively based on the first 100 draws.

These percents should stay relatively similar as more draws are done, approaching the true proportions of each colour better the higher the number of draws. That means 29%, or 290, of the 1000 draws will be green.
