If the last digit in 1.50 is less than 5, then remove the last digit.
If the last digit in 1.50 is 5 or more and the second to the last digit in 1.50 is less than 9, then remove the last digit and add 1 to the second to the last digit.
If the last digit in 1.50 is 5 or more and the second to the last digit in 1.50 is 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the left of the decimal place.
When rounding 1.50 to one decimal place we use One Decimal Place Rule #1. Therefore, the answer to "What is 1.50 rounded to 1 decimal place?" is:
1.5
Use the FOIL method
First 4x × -2x = -8x^2
Outside 4x × -5 = -20x
Inside 3 × -2x = -6x
Last 3 × -5 = -15
-8x^2 - 20x - 6x -15 =
Combine like terms
-8x^2 -26x -15
Answer: 25
Step-by-step explanation:
Turn numbers into whole numbers 3 3/5= 3.60 & 9/10=90
so 90/3.60=25.
Hope this helps!
Answer:
B.
.
Step-by-step explanation:
Total number of marbles = 11.
Since, after choosing the first marble, we are putting it back and then the second marble is chosen.
As, there are 4 shaded marbles.
So, the probability of getting the first marble shaded =
= 
Also, there are 6 odd labeled marbles.
So, the probability of getting the second marble being odd labeled =
= 
So, the probability of getting the first marble shaded and second marble labeled odd =
=
.
Hence, the required probability is
.
Answer:
Step 1:
To find ordered pair solutions, you could create an x and y graph and fill out the x side. Then, plug in an x number to get your y number and graph the ordered pairs to see if they give you a straight line. I'm going to use these numbers: -1, 0, 1, and 2.

![\left[\begin{array}{ccc}-1&?\\0&?\\1&?\\2&?\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26%3F%5C%5C0%26%3F%5C%5C1%26%3F%5C%5C2%26%3F%5Cend%7Barray%7D%5Cright%5D)
Now, let's plug in -1 into the equation first to see what we get for y.

-5 is our y if x was -1.
We do the same for the other three numbers.



Step 2:
With all that done, we can now fill out our table and graph the points.

![\left[\begin{array}{ccc}-1&-5\\0&3\\1&11\\2&19\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26-5%5C%5C0%263%5C%5C1%2611%5C%5C2%2619%5Cend%7Barray%7D%5Cright%5D)
If you graph these points on graph paper / a graphing website, you will see that these points go in a straight line. If you are given an ordered pair already (for example: (3,5)), then all you have to do is plug in the x into the equation (3) and see if the outcome is true (5).

Since they don't equal each other, then (3,5) is false.
Here is the graph for the table above. I hope I helped you!
