Suppose
At the same time, we can write
Note that (just reverse the sum). Let's pair the first terms of and , and the second, and the third, and so on:
Now, each grouped term in the sum on the right side adds to 151. There are 52 grouped terms on that same side (because there are 50 numbers in the range of integers 51-100, plus 50 and 101), which menas
But , as we pointed out, so
Answer:
Roman
Step-by-step explanation:
An easy way to solve this is looking at whether the line has a positive or negative slope. We read graphs from left to right so <u>if the line is increasing from left to right, it has a positive slope while a line decreasing from left to right has a negative slope</u>. Since the line shown is decreasing from left to right, it will have a negative slope and Roman is the only one out of the two that shows a negative slope. To check to see if he's correct, we can check the y-intercept. The y-intercept of the line is 8 and Roman also has 8 written in the expression. Hence, meaning Roman is correct.
Best of Luck!
You can show money as a fraction by taking the amount of cents, and putting it over 100.
Ex. $1.47 = 147 cents
147 cents = 147/100 in fraction form.
17- 6 11/12
borrow from the 17 and use a common denominator
16 12/12 - 6 11/12
10 1/12
