Mary put new tiles on her kitchen floor. The floor measures 6 ft long by 5 ft wide. She used 10 tiles to cover the entire floor each tile was 3 ft long. Write an equation using the variable x to model this situation. What does x represent in the equation?

10x=30

X=30/10
X=3
10x=6x5ft

This is a bit vague. If you always have 10 tiles, then (6/x) * 5 indicates how many tiles will be needed if each is x ft long and 1 ft wide.

Brenda spent half her money at astore.At another store,she spent half her remaining money and$6 more.She had $2 left.How much did Brenda have when she arrived at the store?

To write an equation using the variable "x" to model this situation, we need to express the relationship between the number of tiles used and the size of the floor.

First, we need to calculate the total area of the kitchen floor. The formula for the area of a rectangle is:

Area = length * width

Given that the length is 6 ft and the width is 5 ft, the total area of the floor is:

Area = 6 ft * 5 ft = 30 ft^2

Next, we need to determine the area covered by each tile. Since each tile is 3 ft long, the area covered by one tile is:

Area per tile = 3 ft * 3 ft = 9 ft^2

Finally, we can write the equation:

Total area of the floor = Number of tiles * Area per tile

30 ft^2 = x * 9 ft^2

In this equation, "x" represents the number of tiles used to cover the entire floor.

X=x-x=x
