x < 7
(when changing sides of neg. multipliers, you need to change the sign side, dont fall for that common mistake)
Work:
Multiply a and 7
Multiply a and 1
The a just gets copied along.
7*a evaluates to 7a
8+7*a evaluates to 8+7a
8 + 4 = 12 which goes to 12+7a
(8+7*a)+4 evaluates to 12+7a
***The final answer is 12+7a***

Answer:
1/151200
Step-by-step explanation:
The number of ways to pick an exact order of any 6 different numbers from 10
=
= 10×9×8×7×6×5 = 151200 ways
which means the first one can be any of 10 numbers
The second one can be any of 9 numbers
The 3rd one can be any of 8 numbers and so on
Now the 6th one can be any of 5 numbers
Thus there are 10×9×8×7×6×5 = 151200 ways to choose the number
so the required probability is 1/151200
