Ok so…
The answer is: 15 more marbles
Because
18 divided by 2 is 9
15+9=24
Now Chris has 9
Kevin has 24
24-9=15
Hope this helps:)
21x - 14
Explanation:
you distribute the 7, and first multiply it by 3x to get 21x. Then you distribute the 7 and multiply it by the -2 to get -14.
Hope this helps!
Graph it
On the right side of the graph , go up 9 and go left 8
You'll be paying less for the tables because you're ordering fewer tables: 20 instead of 25.
Find the unit, after-tax price of a table:
$1,706.25
--------------- = $68.25 per table
25
Then, the total that must be paid to purchase 20 tables is
20($68.25/table) = $1,365
Combine like terms then either leave it where you get it or out in standard form
