Answer:
it will take 2 minute 30 seconds
Step-by-step explanation:
Cheeta DATA:
rate = 18 m/s ; time = t seconds ; distance = rt = 18t meters
Gazelle DATA:
rate = 16 m/s ; time = t seconds ; distance = rt = 16t meters
Equation:
gazelle +300 meters = cheetah
16t + 300 = 18t
2t = 300
t = 150 seconds (time for the cheetah to catch the gazelle)
Answer:
7/10 feet/year
Step-by-step explanation:
This straight line graph passes thru (0, 0) and (10, 7).
As x increases from 0 to 10, y increases from 0 to 7. Thus, the slope of this line, which is the unit rate, is m = rise / run = 7/10 feet/year.
7x + 3x - 6 - 4x + 8
6x + 2
A is the answer
I think you meant...
3^(3x-7)=81^(12-3x) (note that 81=3^4) so
3^(3x-7)=3^4^(12-3x)
3^(3x-7)=3^(48-12x) taking log or natural log of both sides show that
3x-7=48-12x
15x=55
x=11/3
