The equation y=1/9x relates proportional quantities x and y.
cluponka [151]

Answer:

x=36 when y=4

Step-by-step explanation:

When y=4, you have to multiply 1/9x by 9 to make x whole and to truly figure out how much it is worth. So if 1/9x =4, you need to multiply 4x9

4x9=36

x=36

The two triangles are similar.
Neko [114]

Given that the triangles are similar.

When triangles are similar, all three pairs of corresponding sides are in the same ratio.

Similarly in the given triangles, the ratio of the corresponding sides are equal.

\frac{8}{2x-2}= \frac{8+6}{3x}

\frac{8}{2x-2}= \frac{14}{3x}

Cross multiplying, we get

8 \times 3x = 14 \times (2x-2)

24x = 28x-28

-4x = -28

Dividing both sides of the equation by -4.

So, we get

x = 7.
