Evaluate the expression y - x + z for x = 22, y = 4, and z = 0.15 y - X + z =
(Type an integer or a decimal.)
S

-17.85

Step-by-step explanation:

=> y-x+z

Putting y = 4, x = 22 and z = 0.15

=> 4-22+0.15

=> -18+0.15

=> -17.85

the answer is -17.85

Step-by-step explanation:

to find the answer first substitute x, y and z by the numbers 22, 4 and 0.15 respectively.

y-x+z

4-22+0.15

-18+0.15=-17.85

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.
