What is the value of x in the equation ? 13x - 2(8+5x) = 12 - 11x

x=2

Step-by-step explanation:

13x - 2(8+5x) = 12 - 11x

The first step is to distribute the -2

13x -2*8 -2*5x = 12-11x

13x -16-10x = 12-11x

Combine like terms

3x-16 = 12-11x

Add 11x to each side

3x+11x -16 = 12-11x+11x

14x-16 = 12

Add 16 to each side

14x-16+16 = 12+16

14x=28

Divide by 14

14x/14 =28/14

x =2

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
