Step-by-step explanation:
2x+3(-7+3x)=12
x=3
y=-7+3x3
y=2
(x,y)=(3,2)
Answer:
For this question, all we need to do is to apply the formular to calculate the distance since we already had the time which is h hours and the speed which is 400 miles per hour:
d = v × t = 400 × h
So the correct answer is number 3.
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
