Answer:

  • B. 308

Step-by-step explanation:

  • Table is given below
  • Find the missing values.
  • The one we are looking for is total of green = y.

                 |<u>              1 -H        |       2-H          |       </u><u>Total</u>

<u>Green       |           170            |          x           |       y       </u>

<u>Purple       |            z              |       284          |       w      </u>  

Total         |            430          |          v            |      852      

  • z = 430 - 170 = 260
  • w = 260 + 284 = 544
  • y = 852 - 544 = 308
  • v = 852 - 430 = 422

Correct choice is B

Hi there friend:)


Your answer would be to add because 'gain" is the clue word to adding because it means adding on to something or means to have or get more of something added on, so when you add 5 + 0.25 you get 5.25, so 5 + 0.25 =
5.25


Sorry if its wrong

Have A Happy Thanks Giving With Family and Friends

I need help please????

Answer:

x = - 1

Step-by-step explanation:

Given

3x + 2 = y and y = - 1

Substitute y = - 1 into the equation and solve for x, that is

3x + 2 = - 1 ( subtract 2 from both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1

This is verified by the point on the graph with coordinates (- 1, - 1)
