In a department store he finds a square rug that has an area of 9 m2. how many of those rugs are needed to cover an area of 36 square meters?

4

Step-by-step explanation:

Divide the total area by the area of a rug to find the number of rugs.

The total area is 36 m²

The area of a rug is 9m²

36m² ÷ 9m² = 4

Therefore 4 rugs are needed to cover an area of 36 square metres.

the distance between point a and point b is 6 units

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
