1. If m = 2, find the value of:
(i) 3m - 5
(ii) 9-5m

(i) 3x2-5=6-5= 1

(ii) 9-5x2=9-10= -1

hope it helps!

3m-5=3×2-5

=6-5

=1

9-5m= 9-5×2

=9-10

= -1

Step-by-step explanation:

You should put the value of m

then by following BODMAS RULE

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.
