keep the inequality sign the same
Answers
Answer: If you multiply an inequality by a positive number keep the inequality sign the same
Explanation: There are certain rules that should be kept in mind while solving the inequality:
1. When a number is added or subtracted from each side of an inequality the direction of the inequality does not change
2. When each side of an inequality is multiplied or divided by a positive number the direction of the inequality does not change
3. When each side of an inequality is multiplied or divided by a negative number the direction of the inequality does change

You have enough wallpaper to cover 240 square feet. If your walls are 8 feet high, what wall length can you paper?
First write down our data:
A = 240 square feet
l = 8 feet
Now we can fill in the formula
240 = 8 × w
Switch sides.
8 × w = 240
Divide both sides by 8.
w = 240 / 8 = 30
Therefore the answer is B.
Wall length of 30 feet
Final answer:
Using the formula A=l•w to solve the wallpaper problem, where the area (A) is 240 square feet and the width (w) is the height of the walls (8 feet), we find that the wall length (length) that you can paper is 30 feet.
Explanation:
The subject of the word problem is finding the wall length you can cover with a given amount of wallpaper. In this case, the area of the wallpaper is 240 square feet, and the height of the walls is 8 feet.
The formula for the area of a rectangle is A=l•w, where A stands for area, l stands for length, and w stands for width. In this case, the 'width' is the height of the walls, which is 8 feet.
To find the length of the wall, we can rearrange the formula to l=A/w and substitute the given values. That means l=240/8, which gives us a wall length of 30 feet.
Therefore, the answer is b. Wall length of 30 feet.

We know that:
1- MLC=KJC.
2- KLM=90.
KLM is composed of KLC and MLC.
This means that:
KLC+MLC=90°
Since MLC=KJC, we can write this as KLC+KJC=90°.
This is the definition of complementary (two angles whose sum is 90 degrees).
