Handles-n-Things is a small enterprise company buying new carpet for their office room. The room is 15 ft. wide and 24 ft. long.
Helen [10]

Hey there!

To find the area, we multiply the length by the width! The carpet will cover the area of the room.

24×15=360

But, the carpeting is sold in square yards, not feet. There are three feet in a yard, which means that one yard is 1/3 feet. Since we have 360 square feet, we will divide it by three to get yards.

360/3=120

Therefore, the office would need 120 square yards of carpeting.

Have a wonderful day!

Please help and can you explain
NISA [10]

Answer:

x = 6

Step-by-step explanation:

first you would put them equal because they have the same angle: 9x + 10 = 2x + 52

subtract 10 from both sides: 9x = 2x + 42

subtract 2x from both sides: 7x = 42

divide by 7 on both sides x = 6

hope this helps! :)
