Answer:
Step-by-step explanation:
We will use two properties to solve this problem,
1). Medians of a triangle bisect the sides of a triangle.
2). Centroid of a triangle divides the medians in the ratio of 2 : 1.
Length of FH = 2 × Length of HX
= 2 × 12
FH = 24
PF : PZ = 2 : 1


PF = 8
GX = GP + PX
GP = 9 [Given]
Since, 
PX =
= 4.5
Therefore, GX = 9 + 4.5
GX = 13.5
Answer:
we conclude that:

Step-by-step explanation:
Given
We have to determine 
so

Thus we conclude that:

To find miles per hour:
3 3/5 miles divided by 4/5 hour
3 3/5 = 5*3 + 3 = 18/5
18/5 divided by 4/5 equals
18/5 times 5/4
The fives cancel out, and we have 18/4 which reduces to 9/2 or 4 1/2 miles per hour :)
C.171
Step-by-step explanation:
4×7(2)-25
4×49-25
multiply 4×49=196-25
then subtract 196-25=171
