sometimes it helps to draw it out...

     (17)
C_______M_________Q
|___________________|
             21

therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===
calculista

we know that

If M is between points C and Q

then

[tex]CQ=CM+MQ[/tex]

[tex]CM=17\ units\\ CQ=21\ units\\MQ=?[/tex]

Solve for MQ

[tex]MQ=CQ-CM[/tex]

Substitute the values in the formula above

[tex]MQ=21-17[/tex]

[tex]MQ=4\ units[/tex]

therefore

the answer is

[tex]MQ=4\ units[/tex]
