Equation a: 3 + 5 = 8
equation b: (3 + 5) / __ = 4
choose the number that will make equation a equivalent to equation b.

2

Step-by-step explanation:

(3+5)/2=4

8/2=4

which is true

The answer is 2.

Step-by-step explanation:

Remeber to always use PEMDAS.

1. (3 + 5) / x = 4 - We do the addition in the parenthesis first.

2. 8 / x = 4 - We now want to find what x means, to do this we divide the answers by the number we already have.

3. 8 / 4 = 2 - Now we can do the initial equation with the number we found to test it.

4. 8 / 2 = 4 - Simple as that :)

the answer for this question is 38

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.
