Answer:
D. y=70x
Step-by-step explanation:
The cheetah was clocked running 70 miles per hour.
i.e. in 1 hour cheetah covered 70 miles
in 2 hours cheetah covered 140 miles
in 3 hours cheetah covered 210 miles
in general, in n hour cheetah covered 70n miles
If y denote the distance covered
and x denotes the time cheetah runs
Then, y=70x
Hence, the equation which shows the relationship between the distance, y, and time, x, the cheetah runs is:
D y=70x
Answer:
20 1/2
Step-by-step explanation:
its 20 and a half because 16+20=36 and you just need to add a half to 20 since your taking it away
Answer:
D and yes
Step-by-step explanation:
+ 1 = -3 If we multiply both sides of the equation by 4 will will get the second equation
(4) + (4) 1 = (4) -3
x + 4 = -12 We solve this for x by subtracting 4 from both sides.
x = -16
Plug -7 into both equations and you will see that it is a solution
+ 1 = -3
+ 1 = -3
-4 + 1 = -3
-3 = -3
x + 4 = =12
-16 + 4 = -12
-12 - -12
Hey!
It says that it is the sum of 3 consecutive odd integers right?
So then we give these numbers some variables to work with like so...
x = 1st number
x + 2 = 2nd number
x + 4 = 3rd number
now set all of them equal to 207
x + x + 2 + x + 4 = 207
3x + 6 = 207
3x = 201
<u>x = 67</u><u /> <u>x + 2 = 69</u><u /> <u /><u /> <u>x + 4 = 71
</u><u>
