Given that 3 x − 5 y = 15
Find y when x = 1
Give your answer as an improper fraction in its simplest form.

y = -

Step-by-step explanation:

Given

3x - 5y = 15 ← substitute x = 1 into the equation

3(1) - 5y = 15

3 - 5y = 15 ( subtract 3 from both sides )

- 5y = 12 ( divide both sides by - 5 )

y = -

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.
