How to find the value of x such that the data set 100, 120, 110, 110, 110 and x has a mean of 120?

x is 130 to get the mean you need to eliminate values until you remain with the values in the middle so me middle values are (110+x)/2=120

110+x=240

x=130

x is 130 to get the mean you need to eliminate values until you remain with the values in the middle so me middle values are (110+x)/2=120

110+x=240

x=130

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
