Answer:
14k²-(53/3k)+5
Step-by-step explanation:
To expand, remove brackets:
1/3(6k-5)(7k-3)=1/3(42k²-53k+15)
=14k²-(53/3k)+5
If there are 4 marbles left over each time, then we can forget about them for now.
So the question is, what is the smallest number than can be divided into 6,7 and 8?
the numbers have only one non-1 divisor in common: both 6 and 8 are divisible by 3.
so for our purposes we can "delete" one 2 and ask:
what is the smallest number than can be divided into 3,7 and 8 ?
There are no more divisors in common, so we just have to multiply them: 3*7*8=21*8=168
and the 4 marbles "extra"? We add them to this sum.
the the smallest possible number in the box is 168+4=172.
Answer: p = 8, -10
Step-by-step explanation: Solve for p by simplifying both sides of the equation, then isolating the variable.
1 hour = 60 minutes
15 minutes = (60/15) = 1/4th of an hour
1/4 = 0,25
<span>15 minutes is 25% of an hour</span>
