Answer:

C is the answer

C ) y = \frac{4 x + 3}{11}

Step-by-step explanation:

2 y - x = \frac{3}{4} ( -y + 1)

(2 y - x ) 4 = 3 ( -y +1)

8 y - 4 x = -3 y + 3

8 y + 3 y = 4 x + 3

     11 y = 4 x + 3

∴ y = \frac{4 x +3}{11}

Step-by-step explanation:

The answers are given in the same line .

Actual                                                      1/3                          2/3

30 inch. by 12 inch                                120 inch²                 240 inch²

30 inch. by 18 inch                                180 inch²                 360 inch²

12 inch. by 15 inch                                  60 inch²                  120inch²

18 inch. by 15 inch                                90 inch²                    180inch²

We  find the areas and multiply by 2/3 to get the answers

30 * 12= 360 inch²

2/3 * 360 = 240 inch²

30 * 18= 540 inch²

2/3 * 540 = 360inch²

12 * 15= 180 inch²

2/3 * 180 = 120 inch²

18 * 15= 270 inch²

2/3 * 270 = 180inch²
