Answer:
A. CB
Step-by-step explanation:
3 x 2 (C is a 3 by 2) matrix can be multiplied to a 2 x 2 (B is a 2 by 2) matrix since C has 2 columns that are equal to the number of rows in the second matrix B.
A way of checking if two matrices can be multiplied is to first check the number of columns the first matrix contains and then check the number of rows that the second matrix contains.
If the number of columns in the first matrix equal the number of rows in the second matrix then that means it is possible to multiply these matrices.
For these questions it's asking you to substitute the value into the equation.
For example question 5 says,
26= y-9;y=35
basically it's saying if y=35, is the equation correct or not.
In this case: 26= 35 -9 is correct.
So your answer is true.

Answer:
p = 10
q = 4
Step-by-step explanation:
10/p = 1
<em>(multiply both sides by p)</em>
10 = 1p
10 = p
250 = 1000/q
<em>(multiply both sides by q)</em>
250q = 1000
<em>(divide both sides by 250)</em>
q = 4
