If 3x > or = 2x+5 then what is 3x-10 > or = 2x -__

To save time, you dont need to write "> or ="

You can simply write ">=" without the quotes.

So 3x >= 10 means "3x is greater than or equal to 10"

we start with 3x >= 2x+5

we want 3x-10 on the left hand side. We already have a 3x. So if we stick a -10 on the left side, we need to do the same thing to the right side to balance things out. We can subtract 10 from both sides to do this

3x >= 2x+5

3x-10 >= 2x+5-10 ... subtract 10 from both sides

3x-10 >= 2x-5

So it looks like a 5 will go in the blank because the negative portion is already taken care of.

r and t.

both are 64 degrees.
