Answer:
6758
Step-by-step explanation:
Number of steps in Monday = 8565 steps
Number of steps in Tuesday = 14707 steps
Number of steps in Wednesday = 15323 steps
Number of steps in Thursday = 9788 steps
Number of steps in Friday = 12482 steps
Formula for range = Highest value – Lowest value
Here, highest value = 15323 and lowest value = 8565
Range of the number of steps = 15323 – 8565 = 6758
Hence, range of the number of steps is 6758 steps.
This statement is true, or else you wouldn't have a sphere.
2.5y + 3x = 27
5x - 2.5y = 5
Align the variables to make solving this easier.
2.5y + 3x = 27
-2.5y + 5x = 5
You can see that the 2.5y and -2.5y cancel each other out. Then add the 3x and 5x, and 27 + 5.
3x = 27
5x = 5
8x = 32
Divide both sides by 8.
x = 4
Now input that x into one of the equations to get y.
2.5y + 3(4) = 27
2.5y + 12 = 27
2.5y = 15
y = 6
The answer to this system of equations is x = 4, y = 6. (4, 6)
