The answer is B because n is equal to the number of notebooks. you can not exceed the amount of money that you have to buy the notebooks
25 less than 5 = 5 - 25
the answer is A. 5 - 25
Less than = subtraction
so the equation means 5 -(less than) 25
the correct answer is 5 - 25
Hope this helps!
12 flips, 11 heads, 1 tails
Let's say there's a 50-50 chance of landing heads.
There are 12 flips and 12 specific outcomes.
The probability is 2^(-12) = 1/4096 = 0.0244%
If the last flip doesn't matter, then the probability would be 2^(-11) = 1/2048 = 0.0488%.
Have an awesome day! :)

The angels in a triangle should be 180° all
85+64+30=179<180
so we should add 1° to the first one
the angels would be 86 64 30
