What is the coefficient of q in the sum of these two expressions? (23q – 34) and (–16q – r) NEED HELPPP
jeyben [28]

Answer:

The coefficient of q is 7

Step-by-step explanation:

The two expressions are

23q-34 and -16q-r.


The sum of the two expressions is


23q-34+-16q-r


When we group like terms the expression will be,


=23q-16q-r-34


When we  simplify the expression will now be


=7q-r-34

The coefficient of q is the constant behind q in the expression.

The coefficient of q is  therefore 7.
