Answer/Step-by-step explanation:

The corresponding side lengths of two triangles are always equal. Apply this in solving for x

4. \frac{9}{6} = \frac{x}{5}

Cross multiply

6*x = 5*9

6x = 45

divide both sides by 6

y = 7.5

5. \frac{10}{8} = \frac{x}{11}

Cross multiply

8*x = 10*11

8x = 110

divide both sides by 8

x = 13.75

6. \frac{12}{x} = \frac{7}{4}

Cross multiply

x*7 = 12*4

7x = 48

divide both sides by 7

x = 6.86 (nearest hundredth)

Solve 9x−y=45 for y.
Taya2010 [7]

So to solve for y, we need to get y alone on one side of the equation. So we are going to subtract 9x from both sides of the equation to get:

-y=-9x+45

And since y is negative, we are going to divide both sides by -1 in order to make the y positive:

y=9x-45
