Question

Does the black line in the figure represent a line of symmetry?

3

Answer

When you are trying to decide if a line represents a line of symmetry you can think about folding the figure across that line. Once you make the fold, do all of the parts line up on top?

If yes, then the line represents a line of symmetry.

If no, then the line does not represent a line of symmetry.

3

This line represents a line of symmetry because if you fold on the black line, then one side would lay on top of the other and the parts would match up.

Question

Justin has shelves in his room. Each shelf holds toys. If Justin has toys, how many toys don't fit on the shelves?

Answer

To solve this problem, we first need to find out how many of Justin's toys will fit on the shelves. If we have shelves, and toys fit on each shelf, we can multiply those two numbers together to find out the total number of toys that will fit. Let's let represent the number of toys that will fit.

Justin has toys, so to find out how many don't fit on the shelves we need to know what is left over, so we subtract. Let's let represent the number of toys left over.
