K/2+9=30 1. Start by getting rid of the number farthest from K
-9 -9 2. The nines cancel out, 30-9=21
K/2 = 21 3. Next, get the 2 away from K
/-2 /-2 4. The 2 cancel out when divided, 21 divided by -2= -10.5
K = -10.5
K=-10.5
The sum of AB and BC is 180 degrees. So 13x - 10 = 180. 13x = 190.
x = 190/13
F(0)=3(0) = 0
f(1) = 3(1) = 3
f(2)= 3(2) = 6
f(3) = 3(3) = 9
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.
