PLEASE HELP ME PLEASE :(

4.85

Step-by-step explanation:

Let's plug in the values for the equation! Let's start off with mike.

y = 4.5 + 0.977(172)

= 4.5 + 168.05

~ 172.55 = Mike arm span

Now let's do George

y = 4.5 + 0.977(165)

= 4.5 + 161.2

~ 165.7 = Mike arm span

172.55 - 165.7 ~ 4.85

*Note I also rounded in the middle

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

answer: 1, 3 and 5 are correct
