The 2008 year book at middleton middle school had 236 candid pictures of students. the 2007 yearbook had 214 candid pictures of students. what was the percent of change in the number of candid student pictures from 2007 to 2008 to the nearest tenth?

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

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
