Emma’s statement makes sense and Charles’ doesn’t, bcuz when you say 0.75 it should be 75 tenths, because it’s less than a whole number, but charles said 7 and 5 tenths, if it’s 7 and 5 tenths, it would be 7.5.

Is 6x and 4x+2 equivalent
Eduardwww [97]

Answer:

Is 6x and 4x+2 equivalent

? No!

Step-by-step explanation:

6x doesn't equal 4x+2

In order for them to be the same you would have to add the same terms example:

4x+2x would equal 6x

Extra explaining:

The only way for those term to be added would be if they had the same variable since only 4x has a variable the 2 cant be added. In math you CANNOT move your variables off of a number and add them back on after.
