Answer: 
Step-by-step explanation:
Complete question is provided in the attachment below.
Given: Jacob and Issac decided to run to the basketball court
Distance between basketball court and school =
miles
miles
Speed =
miles per hour
miles per hour
Since, time = (distance) ÷ ( speed)
Now, the time taken by boys to arrive at the basketball court =
hours

Hence, the required length of time = 
2/3
denominator is increased by a number so 3+a
numerator is doubled so 2(2)= 4
in order for it to be a whole (or 1) then it would have to be 4/4
so 4-3=1
the number is 1
Answer:
x = 12
Step-by-step explanation:
Since the top line is equal to the bottom, you make the equation -
x + x + 4 = x + 16
You subtract an x on both sides because there is one on each side -
x + 4 = 16
Then you subtract the 4 from both sides to get x by its self, which makes
x = 12
