Question

M is between points C and Q. CM=17 and CQ=21. What is MQ?

Answer 1

Answer:  The required length of MQ is 4 units.

Step-by-step explanation:  Given that the point M lies between the points C and Q, where

CM = 17  and  CQ = 21.

We are to find the length of MQ.

Since the point M is between the points C and Q, so we must have

$CM+MQ=CQ\\\\\Rightarrow MQ=CQ-CM\\\\\Rightarrow MQ=21-17\\\\\Rightarrow MQ=4.$

Thus, the required length of MQ is 4 units.

Answer 2

The answer is 21 - 17, which = 4.
Or you could +4 to CM (17) which equals CQ (21)
