Answer:
multiply the first equation by 2
Step-by-step explanation:
24x + 36y = 72
-16x + 8y = 80
48x + 72y = 144
-48x + 24y = 240
96y = 384
y = 4
24x + 36(4) = 72
24x + 144 = 72
24x = -72
x = -3
(-3, 4)
We are given the speed of the shuttle as:
speed = 28,000 miles / hour
We know that:
1 mile = 5280 ft
24 hour = 1 day
Therefore by conversion:
speed = (28,000 miles / hr) * (5280 ft / 1 mile) * (24 hr
/ day)
speed = 3,548,160,000 ft / day
In 2 significant figures:
<span>speed = 3.5 x 10^9 ft / day</span>
