Select all the equations that represent this situation. Diego has run 2/3 of a race's distance. He has run 8 & 1/2 kilometers. How long is the whole race?

8 & 1/2 divided by 2/3 = ?

2/3 divided by 8 & 1/2 = ?

2/3 x ? = 8 & 1/2

8 & 1/2 x ? = 2/3

8 & 1/2 times 3/2 = ?

8 & 1/2 x 2/3 = ?

Step-by-step explanation:

Diego has run  2/3 of a race's

Let total distance of the race = y

He has run 8 & 1/2 kilometers.

This means 2/3 of y = 8 & 1/2 km

How long is the whole race?

2 / 3  x  y  = 8 & 1/2

The following equations can be used to calculate the distance of the whole race;

8 & 1/2 divided by 2/3 = ?

2/3 x ? = 8 & 1/2

8 & 1/2 times 3/2 = ?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
