Answer:
Step-by-step explanation:
In general, graphs that go from lower left to upper right have a positive slope (think of it as going up the stairs...positive), and graphs that go from upper left to lower right have a negative slope (think of it as going down the stairs...negative). I don't see graphs here but use this general idea and you'll be fine. Of course, this applies to graphs of lines of the form y = mx + b.
twelve multiplied by six equals seventy two. Three multiplied by two equals six. Therefore seventy-two plus six equals seventy-eight
3.42. 342 hundredths is a decomposition of 3.42. On the place value chart if you write 3 ones 4 tents and 2 hundredths and then decompose it to a unit you get 342 hundredth. Hundredth is the unit.
