Hey there! :)
3 - (-2) = ??
Let's keep in mind that a negative times a negative is always a positive!
In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!
So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!
In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!
Therefore, our answer is 5.
3 -(-2) = 5

Answer:
0, 5x
Step-by-step explanation:
0 in the first box
5x in the second box
We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
Answer:
200 dollars
Step-by-step explanation:
Let's say p equals the cost price of the article. Since the man made 25% profit, that means he got 100% of what he originally paid plus another 25% of what he originally paid. In other words, he sold the article for 125% of the original price. Converting that to a decimal we get:
250=p*1.25
Some simple division gets us a cost price of 200 dollars.
Answer:
5 people
Step-by-step explanation:
First, you subtract 50 from 800 bc the luggage rack is 50 pounds. Then, you do 750/150. You should get 5 as your answer.
