Answer:
(6r+7)+(13+7r)=13r+20
(13-1/2r)-(1-r)=12-1/2r
(-8-r)+(2r-4)=-12+r
Last one is r-13/6
Step-by-step explanation:
A)-1/2 is the slope. what ever is next to x is the slope
Heathe lives halfway up: 42 / 2 = 21st floor.
Raveen = 42 x 4/7 = 168/7 = 24th floor.
Alveera = 42 x 3/14 = 126/14 = 9th floor.
Rafi = 42 x 4/6 = 168/6 = 28th floor.
Suha = 28-24 = 4 /2 = 2 = 24+2 = 26th floor.
Arabi = 42 x 2/3 = 84/3 = 28th floor
