What is the mean of 82, 4, 94, 4, 60, 91 and what is n2 = 81 ; What is the value of n?
-4n = 16; What is the value of n?

1. The mean is 55.83

2. when n2=81 then n=40.5

3. when -4n=16 then n = -4

Step-by-step explanation:

1. you add all the numbers together then divide the sum by 6

2. divide both sides by 2

3. divide both sides by -4

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
