Answer:
18/3=6 which means the hot air balloon travels 6 miles per hour
6*(3/4)=4 and 1/2 miles
To evaluate these you would multiply the two fractions together.
For example:
5*24
____
8*1
This problem uses the intersecting chord theorem. In this case, it states that:
ML * LE = SL * LI
With this knowledge, we can fill in the known values and solve for the unknown ML.
ML * 12 = 4 * 9
ML * 12 = 36
ML = 36/12
ML = 3
Thus, the missing value is 3.
It is 10 because of the equation on the left
