4 to 7 = 4/7

5/8 is not.

12/20 = 6/10 = 3/5 . It is not equivalent.

8:14 = 4 : 7 . It is equivalent

5 to 10 = 1 to 2. It is not.

16/28 = 8/14 = 4/7. It is equivalent.

9 to 16 = 9 to 16. It is not equivalent.

So only 8:14 and 16/28 are equivalent to 4 to 7.

What is the value of x in the figure?<br><br> Enter your answer in the box

Tcecarenko [31]

Answer:

x =68

Step-by-step explanation:

We know that x+22 = 90 because the sum of the two angles is a vertical angle to the right angle and vertical angles are equal.

x+22 =90

Subtract 22 from each side

x+22-22 = 90-22

x =68
