Solving a compound inequality for this solution gives solution as;
13 daytime cameras and 7 flash cameras or 7 daytime cameras and 13 flash cameras
<h3>How to solve inequality problems?</h3>
Let the number of daytime cameras be x
Let the number of flash cameras be y
Thus, we have;
x + y = 20 ------(1)
Now, daytime cameras costs 2.75 dollars and the flash camera costs 4.25 dollars and you want to spend between 65 and 75 dollars, inclusive. Thus, the inequality to represent this are;
2.75x + 4.25y ≥ 65 and 2.75x + 4.25y ≤ 75
Solving the 3 compound inequalities simultaneously, we can say that the approximate values of the numbers of cameras are;
13 daytime cameras and 7 flash cameras or 7 daytime cameras and 13 flash cameras

Answer: He needs 1456 feet of wood to complete his home project.
Step-by-step explanation:
1. You know that he needs 13 pieces of wood to complete his home project. Each one of the pieces is 112 feet long.
2. Therefore, to calculate the quantity of wood he need to complete the project (which you can call ), you need to multiply 13 pieces by the the lenght of each one of them (12 feet), as you can see below:
3. Therefore, he needs 1456 feet of wood.
15/4 is the correct answer
I think it’s 9.3 hope that helps
1 6
--- = ---
a 18
- simplify 6/18, which should be 1/3. therefore, a = 3.
