Answer:
x = (5,3)
Step-by-step explanation:
the quadratic formula is x =( -b±√(b^2-4ac))/2a
to solve for x, a=1, b=-8,c=15
x =( -(-8)±√((-8)^2-4*1*15))/2(1)
x=8 ± √(64-60))/2(1)
x=(8 ± √(4)) / 2
x=(8 ± 2) / 2
solve with '+'
x=(8 + 2) / 2 = 10/5 = 5
solve with '-'
x=(8 - 2) / 2 = 6/2 = 3
x = (5,3)
Answer:
3*45=135 minutes.
Step-by-step explanation:
Hello there!
Start by seeing if there is an equal rate in the qmount of people that we are working with.
27/9=3 (so there's one)
3*45 (the amount of time when 9 people are in line)= 135 minutes
Have a great day!
It is 5:9 in simplest form
The easiest way is a successive division by 4:
1st division: 2032/4 = 508 and 0 (0 is the 1st Remaining)
2nd division 508/4 = 127 and 0 (0 is the 2nd Remaining)
3rd division 127/4 = 31 and 3 (3 is the 3rd Remaining)
4th division 31/4 = 7 and 3 (3, is the 4th Remaining)
5th division 7/4 = 1 and 3 (3 is the 5th Remaining)
Now you write the last quotient (the 5th) , that is 1 and add to it all remaining starting from the 5th , backward to the 1st remaining,
