First, you must distribute 2(3x-1).
To do that, you will multiply 2•3x, and 2•-1 because you are taking the number outside of the parentheses and multiplying (distributing) it to all the numbers inside
After distributing, the left side of your inequality will be 6x-2
Now you have

To find the value of x, you must subtract an x value from both sides of the equation, as well as a constant from each side.
so you have

And that will make the equation

Now, divide the variable side, ***BUT, because you are dividing by a negative number in an inequality, the inequality will switch sides.
Then, the value of x is greater than or equal to 2
A, 39
You can get the average score by adding up all the total scores, (33, 41, 33, 45 and 43) and dividing that by the total number of scores, 5. 195 (total score)/5 (number of scores)= 39.
0.008 i think this is the answer
-45x+72
you multiply the 9 by everything in the parentheses
Answer:
9 songs
Explanation:
Given:
The slideshow is 31 whole number 1/2 minutes long
convert to an improper fraction
31×2+1/2 = 63/2
The songs are each 3 whole number 1/2 minutes long
convert to an improper fraction
3×2+1/2 = 7/2
To find the number of songs that Marcus is picking to play during a slideshow, divide the slideshow by the long of one song
(63/2) / (7/2)
= 9 songs.
