Answer:

1) C) 2) B)

Step-by-step explanation:

First one is just times them together get 12root(a^2b^2) = 12ab.

Second question, you use equation 1 to minus equation 2 get 2x = 6, then x = 3, then substitute it into either equation, for example the first one get -7*3 +  5y = 24, then solve for y, can get y = 9, so B) is correct answer.

If it is helpful, plz give me Brainliest.

If a+2b/a-b =2/3 then b/a=?​
Dominik [7]

Answer:

\frac{b}{a} = - \frac{1}{8}

Step-by-step explanation:

Given

\frac{a+2b}{a-b} = \frac{2}{3} ( cross- multiply )

2(a - b) = 3(a + 2b) ← distribute parenthesis on both sides )

2a - 2b = 3a + 6b ( subtract 3a from both sides )

- a - 2b = 6b ( add 2b to both sides )

- a = 8b ( divide both sides by 8 )

- \frac{1}{8} a = b ( divide both sides by a )

- \frac{1}{8} = \frac{b}{a}
