It is 7.5 because it’s quick maths
Mixed number fraction:
1 1/7
Answer:
x = 4.5 or rounded 5
Step-by-step explanation:
Because they are equal you can make the equation:
x/2 = 18/8
this means that 8 divided by 2 equals (4)
what 18 divided by x is (4)
this means 4 times x = 18
4x = 18
/4 /4
x = 4.5 ft
You are looking for the shaded region that would be contained in both of the inequalities.
You have:
![x+y \leq 80](https://tex.z-dn.net/?f=x%2By%20%5Cleq%2080)
![5x+10y\ \textgreater \ 500](https://tex.z-dn.net/?f=%205x%2B10y%5C%20%5Ctextgreater%20%5C%20500)
If you graph an shade the correct half-plane for those equations, you will see there is a triangular region on the left side of the first quadrant.
