<em><u>An inequality that shows the distance Johnathan could of ran any day this week is:</u></em>
![x\leq 3.5](https://tex.z-dn.net/?f=x%5Cleq%203.5)
<em><u>Solution:</u></em>
Let "x" be the distance Johnathan can run any day of this week
Given that,
Johnathan ran 5 days this week. The most he ran in one day was 3.5 miles
Therefore,
Number of days ran = 5
The most he ran in 1 day = 3.5 miles
Thus, the maximum distance he ran in a week is given as:
![distance = 5 \times 3.5 = 17.5](https://tex.z-dn.net/?f=distance%20%3D%205%20%5Ctimes%203.5%20%3D%2017.5)
The maximum distance he ran in a week is 17.5 miles
If we let x be the distance he can run any day of this week then, we get a inequality as:
![x\leq 3.5](https://tex.z-dn.net/?f=x%5Cleq%203.5)
If we let y be the total distance he can travel in a week then, we may express it as,
![y\leq 17.5](https://tex.z-dn.net/?f=y%5Cleq%2017.5)
Answer:
2400 cm^2
Step-by-step explanation:
The surface area for a cube is just 6* area in one face (As there are 6 faces), so 6*20^2 = 6*20*20 = 2400 cm^2
