Answer:
26
Step-by-step explanation:
5 × 4 = 20 (rectangle)
8-5 = 3 (triangle)
3×4÷2 = 6
20+6 = 26
So for this one all you have to do is find the average. Simply do 25 divided by 2 to get 12.5 miles per hour.
The range is the difference between the lowest number and the highest number.
If x was the lowest number, then the highest number shown is 49
X = 49- 58 = -9
If x was the highest number, the lowest number given is 3
X = 3 + 58 =61
The two values would be -9 and 61

This can be rewritten as: 
Also, since 

We know that 

Hence, Option C would the answer.
Answer:
There were 10 people in team one.
Step-by-step explanation:
Let x= team one.
Let y= team two
Because there four times less people in team one than in two we know that x=(1/4)y
After 6 people quit and 12 people transfer from team two, the two teams become equal. Therefore, x + 12 = y - 6 - 12.
You can then insert the initial equation for x into the second equation and know that there were 10 people in team one and 40 people in team two.
