Answer 1

average*

Answer 2

Average of 4 values \(a,b,c,d\) is \(\frac{a+b+c+d}4\). Try to use this.

Write the average of your values right here.

Answer 5

(p+2s)+(r-q)+(2q+5)+(7-s)/4

Answer 8

Answer 9

i thought u asked for the average of p q r and s

Answer 10

What is the problem for you now?

Answer 11

how to find the average of that using 16

Answer 12

because q+ r+ p+ and s = 16

Answer 13

Try to simplify this ((p+2s)+(r-q)+(2q+5)+(7-s))/4.

Answer 14

\[p+2s+r-q+2q+5+ 7-s=12+p+q+r+s=12+16=28 \]\[\frac{28}{4}=7 \]

Answer 15

p+s+r+q+7/4

Answer 16

Do you see the last step to get the answer?
