(2-y)/(y+7)=3/5 what is the answer

1 answer:

3 0

Multiplying both sides by y+7, we get 2-y=(3y+21)/5 and then by multiplying both sides by 5 we get 10-5y=3y+21. After that, subtract 21 from both sides as well as add 5y to both sides to get -11=8y, so divide by 8 to get -11/8=y

Which table shows a proportional relationship between x and y

Tomtit [17]

Answer:

The answer is B (1 , 3) , (2 , 6) , (4 , 12) , (5 , 15)

Step-by-step explanation:

∵ X : 1 , 2 , 4 , 5

∵ Y : 3 , 6 , 12 , 15

∵ 2/6 = 1/3

∵ 4/12 = 1/3

∵ 5/15 = 1/3

∴ 1/3 = 2/6= 4/12 = 5/15 = 1/3 ⇒ all are proportion

∴ Answer B is in proportional relationship
