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.

Judy pays $29 for 8 gallons of gas and 2 bottles of water. Carmen pays $45 for 12 gallons of gas and 4 bottles of water. How muc
Dmitry [639]
G=gas
w=bottle of water

8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.

-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25

Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.

12 (3.25) + 4 (1.5)=45
39 + 6=45

One bottle of water is $1.50, while one gallon of gas is $3.25.
