5x-2y=30 complete the missing value in the solution to the question (8, )
natali 33 [55]

Answer:

(8,5)

Step-by-step explanation:

5x-2y=30

lets substitute "8" as x and see where that takes us

5(8)-2y=30

40-2y=30

subtract 40 on both sides

-2y=-10

divide by "-2" on both sides

y=5

(8,5) is your answer

MissTica

Answer:

It was a rainy day , but Joan and I had planned a trip. Joan wanted to go to the beach for a swim. I wasn't sure if we should go.

"I think we should wait a little longer , at least until the rain shows some signs of slowing down," I suggested.

"We can't swim without getting wet anyway," replied Joan, questioning my choice of swimsuit , the one my mom had bought at a secondhand store.

sattari [20]

Answer:

Step-by-step explanation:

Comment

There are 4 cups in a quart.

There are 12 cups in x quarts.

Solution

4/12 = 1 / x                               Cross multiply

4x = 12*1                                  Combine

4x = 12                                     Divide both sides by 4

4x/4 = 12/4

x = 3 quarts

Answer

3 quarts.
