Question

PLEASE HELP SOLVE THIS!!!!!

Answer 1

Explanation:

• 22

Let's calculate the expression khowing that m= 1 and n = 5

• m-
  `(m+m)/(2)` -n
• m-
  `(2m)/(2)`-n
• m-m-n
• 0-n
• 0-5
• -5

• 20

Let's calculate the expression khowing that n= -7 and p= - 6

• 
  `(p(p+n^(2)) )/(6)`
• 
  `(-6(-6+(-7)^(2)) )/(6)`
• 
  `(-6(-6+49))/(2)`
• 
  `(-6*43)/(6)`
• -1*43
• -43

• 21

Let's calculate the expression khowing that n = -6 and m = -1 and p = -10

• mp-(p-(m-n))
• mp-(p-m+n)
• mp-p+m-n
• (-1)*(-10)-(-10)+(-1)-(-6)
• 10+10-1+6
• 20-1+6
• 19+6
• 25

Answer 2

20) -43

21) 25

22)-9

Explanation:

20) -6 (-6 + 49)/6 = -43

21) 10 - (-10 - (-1 + 6)) = 25

22) 1 - 10/2 - 5 = -9
