−t=9(t−10)

pls show work too thank u so much

t = 9

Step-by-step explanation:

Step 1:

- t = 9 ( t - 10 )          Equation

Step 2:

- t = 9t - 90       Multiply

Step 3:

- t + 90 = 9t        Add 90 on both sides

Step 4:

90 = 10t      Add t on both sides

Step 5:

t = 90 ÷ 10       Divide

t = 9

Hope This Helps :)

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.
