The tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a chess tournament starts at 12:30 p.m. and ends at 5:00 p.m.
The difference between 12:30 p.m. and 5:00 p.m. can be calculated after changing time into 24 hours clock
12:30 p.m. = 12 hours 30 minutes = 12.50
5: 00 p.m. = 17 hours 00 minutes = 17.00
Difference between them:
= 17.00 - 12.50
= 4.5 hours
4.5 < 5
Thus, the tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.

A) Divide the total height by the average height:
26.4 / 1.2 = 22 total boys.
B) Divide total feet by total time:
440 feet / 20 seconds = 22 feet per second.\
Because the submarine is diving the rate would become negative 22 feet per second.

Answer:
the answers are correct what do you need help with?
Step-by-step explanation:
We are looking for k in the equation
(x+4)(x+k/4) = x^2+7x+k
The left hand side expands to:
x^2+(4+k/4)x+k = x^2+7x+k
Comparing coefficients for the linear terms, we have the equation
(4+k/4)=7
Solving for k:
16+k=28
k=12
Thus the number to be subtracted is 15-k=15-12=3
