First, we'll want to write out the equation
then reduce what we can
so this means n can equal any whole number between 9 4/9 & 12, which gives us the options of {10,11}
Answer:
Graph these points listed below
Step-by-step explanation:
Graph the following points:
(6 am, 50)
(9 am, 59)
(1 pm, 63)
(6 pm, 63)
(8 pm, 59)
(12 am midnight, 58)
Answer:
If there is 1 at the top, then you have 1, then 2, then 3, etc.
total number of oranges equals:
1 + 2 + 3 + ... + 16 + 17 + 18 <-- stop at 18 because this is the number of oranges at the base
You can use the formula:
sum of first n numbers = n*(n + 1)/2
-->
18*19/2 = 9*19 = 171
or you can figure it out (basically derive the above formula):
you have:
1 + 18 = 19
2 + 17 = 19
3 + 16 = 19
...
How many pairs do you have? Well, it's just the number of numbers: 1-18 = 18 numbers (divide by 2) = 9 pairs)
9 pairs of 19 = 9 * 19 = 171
Hope this helps!
Step-by-step explanation:
Answer:
The equation is
and the graph looks like this
I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:
7 * 18 + 45 / 3 - 2 = 139
