Step-by-step explanation:
If Rafael practices 3/4 of an hour each day for three days he will have had 3/4 of an hour practice after day 1, 1 1/2 hours of practice after day 2 and then 2 1/4 hours of practice after day 3.
3 x 3/4 = 9/4
9/4= 2 1/4

Answer:
Step-by-step explanation:
So the two lines before and after the expression means absolute value, or modulus of, knowing this, it means that the answer must always yield positive. So if x-6 is positive, it will stay positive, if x-6 is negative, it will turn positive, therefore it can never yield a negative value.
Now im assuming the second question is meant to be absolute value of x-5 is less than 0, because it makes no sense otherwise.
So now knowing that x-5 is always positive, or 0, but this inequality only wants less than 0, this means there are no solutions for the inequality.
