Answer:
1000
Step-by-step explanation:
area of rectangle = width x length
Given:
- width of floor = 40 m
- length of floor = 50 m
⇒ area of floor = 40 x 50 = 2000 m²
Given:
- width of tile = 1 m
- length of tile = 2 m
⇒ area of tile = 1 x 2 = 2 m²
Number of tiles needed = area of floor ÷ area of one tile
= 2000 ÷ 2
= 1000
Hi there!
If you solve for

in this problem you would end up with a result of

. To find

you need do the following:
First, subtract 11.45 from both sides:


Next, divide both sides by -1.2:

To get the end result of:

-Your friend, ASIAX
You will at 7 to both sides and then divide 2 on both sides to find x. :)
2x-7=3
+7=+7
—————
2x = 10
— —-
2 2
X = 5
