I need help with numbers 20,21,and22
julsineya [31]

Answer:

20) the answer is -43

21) the answer is 25

22)the answer is -5

Step-by-step explanation:

20) \frac{p(p+n^{2})}{6}

n=-7

p=-6

we have:

\frac{-6*(-6+(-7)^{2})}{6}\\\\\frac{-6*(-6+49)}{6}\\\\\frac{-6*(43)}{6}\\\\\frac{-258}{6} \\-43

21) mp-(p-(m-n))

m= -1     n=-6   p=-10

-1*-10-(-10-(-1-(-6)))

10-(-10-(5))

10-(-15)

10+15=25

22) m-\frac{m+m}{2} - n

m=1   n=5

1- \frac{1+1}{2} -5

1- 2/2 -5

1-1-5 =-5

What is the solution to –2(5y – 5) – 3y ≤ –7y + 22?
Gre4nikov [31]
-2(5y - 5) - 3y < = -7y + 22

-13y + 7y < = 22 - 10
-6y < = 12
y > = -12/6
y > = -2....answer B
