Answer:

1.5

Step-by-step explanation:

Use similar ratios. 5/4=x/6. Use cross multiplication. 30=4x. Divide by 4 to get x by itself. x=7.5 THIS IS NOT THE ANSWER!! This is the entire side length. Subtract 6 from this to get x. 7.5-6=1.5. x=1.5

Answer:

x = 3/2

Step-by-step explanation:

We can use ratios to solve

6 6+x

-------- = -----------

4 5

Using cross products

6*5 = 4 * (6+x)

30 = 24 + 4x

Subtract 24 from each side

30 -24 = 24+4x-24

6 = 4x

Divide each side by 4

6/4 = 4x/4

3/2 = x

Answer:

11/35

Step-by-step explanation:

First, you would have to make a common denominator. To do this, multiply these 2 denominator, 5 and 7. You should get 35. Then, you would have to make the numerator equal to the denominator. In this case, multiply 3 to 7 and 2 to 5. Now you have 21/35 and 10/35. Now subtract 21 from 10, and simplify if needed. I hope this helps!
