Which property justifies this statement?

if x=y+2x=y+2 and y+2=8y+2=8, then x=8x=8.

symmetric property of equality

addition property of equality

subtraction property of equality

transitive property of equality

option D

Transitive property of equality

Explanation:

Transitive property of equality justifies the statement:

x=y+2 , y+2=8 then;  x= 8

Transitive property of equality states that if we have two things that are equal to each other and the second thing is equal to a third thing then, the first thing is also equal to the third thing.

In mathematical terms: if a=b and b=c then a=c.

As per the given statement:

a = x , b= y+2 and c= 8

then,

a=b i.e, x=y+2 and

b=c i.e, y+2 =8 then

by using transitive property of equality, we get;

a=c i.e, x=8

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

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.
