5 + (-3) - 6
------------------------
Let's do the first part
5 + (-3) whenever you see a problem where you add a negative number just think of it as subtracting
5 - 3 = 2
-------------------------------------------
2 - 6 = -4
-4 is your answer
The answer to this question would be the decimal 5.4
Answer: he has 1 orange balloon
Step-by-step explanation:
Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286
And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
