Answer:

C

Step-by-step explanation:

a girl scout has (5x-12) boxes of cookies and sells (3x+18) of them. Write an expression to represent the amount of boxes she has left. i need help.

Answers

Answer:

2x - 30

Step-by-step explanation:

You have to subtract 3x + 18 from 5x - 12:

=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30

The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined

Answer = 2x - 30

(5x-12)-(3x+18)

Simplified becomes 2x-30

Answers

The answer would be mode= 16, Median= 16, mean=16.91, range=8. The mode is which number on the number line has the most dots on it, in this case it’s 16. For the mode you would go from side to side and cross each dot off till you reach the middle. And once again in that case it’s 16.
mode = 16 median = 16 mean =16.9 and range=8.

Last question:

Answers

Answer:

y=-3x+7

Step-by-step explanation:

Rise/run

To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.

As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.

Plug your answers in and your equation should be y=-3+7.

You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.

Hope this helps :)
