Answer:
67,600
Step-by-step explanation:
For the first and last two characters, there are ten possible digits (0 through 9) for each character.
For the second through sixth character, there are 26 possible letters (A through Z) for each character.
The number of all possible license plate combinations "n" is given by the multiplication of each digits range of possible outcomes:
Since there are no restrictions for repeated characters, there are 456,976,000 different license plate numbers are possible.
2x + 39 = 77 is the equation trnaslated, thne you subtract 39 from both sides to get 2x = 38 then divide both sides by 2 to get x = 19. the number is 19
You would need to know how much it cost to rent each type of tube in order to solve this problem.
One of the equations would be xx+yy=15
The number of single tubes plus the number of cooler tubes is 15.
If you know how much each tube cost, simply put the cost in front of the xx/yy and set it equal to 270$. For example, if the single tubes cost 15$ and the cooler tubes cost 20$, then the equation would be 15xx+20yy=270
