(2z−3) /5 − (z−6)/4 =3

z = 14

Step-by-step explanation:

Step 1: Write equation

(2z - 3)/5 - (z - 6)/4 = 3

Step 2: Solve for z

Step 3: Check

Plug in z to verify it's a solution.

(2(14) - 3)/5 - (14 - 6)/4 = 3

(28 - 3)/5 - 8/4 = 3

25/5 - 2 = 3

5 - 2 = 3

3 = 3

Hi there!

Step-by-step explanation:

Ok this should be easy, lol!

⇒First you going to simplify both sides of the equation.

      ⇒Then Distribute.

     -     ⇅⇅     -

⇒Now combine like terms.

⇒Second you're gonna subtract 9/10 from both sides.

⇒Now, for the last step, multiply both sides by 20/3.

Now you understand why z = 14!

Have a good day/night!

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.
