Hailey wants to hire someone to paint her house. She researched several independent painters who provided information about the

average amount of time it takes them to paint a certain number of square feet of wall space. The three painters with the top ratings are listed in the table below, along with the information they provided.
Name Area Painted
(square feet) Time
(hours:minutes)
Richard 288 45
Gerard 825 2:12
Matthew 992 2:35


Part A: Calculate the unit rate for each painter.

Part B: Compare each pair of painters (Richard with Gerard; Gerard with Matthew; Matthew with Richard), and state whether their rates are in a proportional relationship or not (and why) using their respective unit rates as evidence.

PLEASE HELP ME :(<br> God bless.

Answer:

x - 99 ≤ -104 → 2nd line

x - 51 ≤ -43 → 1st line

150 + x ≤ 144 → 4th line

75 < 69 - x → 3rd line

Step-by-step explanation:

Ugh! Wow, this is going to be tedious, thanks alot, bro (jk, I got your back).

x - 99 ≤ -104

 + 99   + 99

x ≤ -5

There should be a line going from -5 to negative infinity (AKA the left) with a FILLED circle. So, the second one is correct.

x - 51 ≤ -43

 + 51   + 51

x ≤ 8

There should be an arrow with a FILLED circle going to negative infinity (AKA the left). So, the first one is correct.

I'm going to take a shortcut and notice that one of the lines has a filled circle while the other one has an empty circle. So the empty circle must relate to the question without a ≤ or ≥, but with a < or >. We see that 75 < 69 doesn't have ≤ or ≥ but a '<.' So this one must have the empty circle, which is on line 3. The last equation has to be on line 4.
