Answer:

19

Step-by-step explanation:

This was done the normal way of multiplying and dividing first:

If p=1 and q=4, evaluate the following expression:

4q − p/p + q​ = ?

4(4) - 1/1 + 4 = 16 - 1 + 4 = 19

If you wanted to do the addition and subtraction first, the equation would have been:

(4q - p)/(p + q) = ?

(4(4) - 1)/(1 + 4) = 15/5 = 3

With the parentheses, the order of operations is done in the parentheses first.

Answer:

3

Step-by-step explanation:

You can just put in the values of p and q into the expression.

\frac{4q-p}{p+q} = \frac{4(4)-1}{1+4}

       = \frac{16-1}{1+4}

       = \frac{15}{5}

       = 3

8y - y + x + 3x simplified
vredina [299]

Answer:

7y+4x

Step-by-step explanation:

1. So the -y is 1 so you subtract one from the 8 which is 7.

2. x is also like a one so that would also equal 4
