Let the number of hats they sold be x and the number of t shirts they sold be 23-x.
12x + 10(23-x) = 246
x = 8
The number of hats they sold is 8.
23-8= 15
The number of t shirts they sold is 15.
The first contract can go to any of 12 firms. The second can go to any of the remaining 11 firms, and so on. Finally, the 4th contract can go to any of the 9 firms that don't yet have a contract.
The number of ways the contracts can be awarded is
... 12×11×10×9 = 11,880
Answer:
see attached graph
Step-by-step explanation:
You graphs look fine. The only thing I can think of without seeing the question itself, its that perhaps the teacher wants them on the same graph?
Firstly, add 7 on both sides of the equation:
Next, before you can subtract 3/4x on both sides, you first have to find the LCD, or lowest common denominator, of 2 and 4. To find it, you would list the multiples of both and the lowest multiple they share is their LCD. In this case, the LCD is 4. Multiply 5/2 by 2/2 and 3/4 by 1/1:
Now subtract 3/4x on both sides of the equation:
Lastly, multiply both sides by 4/7 and <u>your answer will be x = 12.</u>
Answer:
3/6x • 4/6x
12/6x
2x
Step-by-step explanation:
you would change both fractions to have the same denominator then simplify if needed
