Answer:
Joshua walked 48 feet in total.
Step-by-step explanation:
To find the total distance we need to sum every distance that he walked. We have:
- First: Joshua walked down the hall to the door = 14 feet
- Second: He continued in a straight line out the door and across the yard to the mailbox = 24 feet
- Third: He came straight back across the yard and stopped to pet his dog = 10 feet
Hence, the total distance is:
![d_{T} = d_{1} + d_{2} + d_{3} = 14 ft + 24 ft + 10 ft = 48 ft](https://tex.z-dn.net/?f=%20d_%7BT%7D%20%3D%20d_%7B1%7D%20%2B%20d_%7B2%7D%20%2B%20d_%7B3%7D%20%3D%2014%20ft%20%2B%2024%20ft%20%2B%2010%20ft%20%3D%2048%20ft%20)
Therefore, Joshua walked 48 feet in total.

Answer:
15
Step-by-step explanation:
Let, x, represent the value of Dave's markers. You then make the equation (5x+x=18) because both markers combined is 18 and Sheila has 5 times the markers of Dave so her value would represent 5x. Solving the equation would get you x=3 BUT THAT IS THE VALUE OF DAVE'S MARKERS! The question asks for Sheila's with is 5*3. So the answer is 15 markers.
Answer:
-4.5
Step-by-step explanation:
![6x+5.5=3x-8\\](https://tex.z-dn.net/?f=6x%2B5.5%3D3x-8%5C%5C)
![6x-3x=-8-5.5](https://tex.z-dn.net/?f=6x-3x%3D-8-5.5)
![3x=-13.5](https://tex.z-dn.net/?f=3x%3D-13.5)
![x=\frac{-13.5}{3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-13.5%7D%7B3%7D)
![x=-4.5](https://tex.z-dn.net/?f=x%3D-4.5)
You could do -1/-2 times -5/-4 which would be 5/8
