4. The point (0, 0) is a solution to which of the following system(s)? (x+2y = 8
(x+2y = 8 (x+2y <8
a. 1-4x-y=4
b. 1-4x - y<4
c. 1-4x - y24
(x+2y >8
|--4x - y >4
d.

the answer is d

step-by-step explanation:

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.

wow ok so the answer is 1k or just k

because of combining like terms xd
