B)

d)

9) I'm not really sure how to answer it, but I guess like 2.1, 2.2, 2.5, etc.,
10)


so {5, 6, 7, 8} is the answer
11) for some reason it won't let me insert a picture but put place

above 2, and then place

above 3, and then place

in between 2 and 3, but place it a little closer to three since

12) place

between 2 and three, but closer to two since

and also

and for number 13) the square root of 144 is 12, and the square root of 169 is 13, so any numbers between 12 and 13 will work.
I hope this helped and if not, message me and ill try to explain!
Answer:
Solving for t : t=5+2r/5
Solving for r : r=-25/2+5t/2
Step-by-step explanation: Move all of your terms that don't contain r to the right side and solve. Move all terms that don't contain t to the right side and solve.
Hope this helps you out! ☺ I just solved it and I don't have any choices to go off of and so I just solved it. Sorry if it's wrong. ☺
Answer:
y = -13x + 4
Step-by-step explanation:
You want to put it in the form y = mx + b where m is the slope and b is the y-intercept (For example, in the equation y = 2x + 3 the slope is 2 and the y-intercept is 3)
Since the slope is -13, m = -13.
Since the y-intercept is 4, b = 4.
This means the equation is y = -13x + 4
