Complete question :
Point P is shown on the number line below. The distance between point Q and point P is 6 1/2 units. Which number could represent point Q?
A) -9 1/2
B) 1 1/2
C) 2 1/2
D) 10 1/2
Answer:
1 1/2
Explanation:
To obtain the possible position of point Q:
Add or subtract the distance between the points to the position of point P on the number line ;
Point P is located at - 5
Therefore, point Q will be located at :
Either :
Point P + 6 1/2 = - 5 + 6.5 = 1 1/2
Point P - 6 1/2 = - 5 - 6.5 = - 11 1/2
From the option ;
Q = 1 1/2
