The number of hours that students have to work on homework will be 1/3 hours.
<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
Mr. K's maths class is 1 and 1/4 hours long.
After working problems on the board for 55 minutes or 11 / 12 hour.
He gave the students the rest of the class period to work on homework.
Then the number of hours that students have to work on homework will be
⇒ 1 + 1/4 - 11/12
⇒ 5 / 4 - 11/ 12
⇒ (15 - 11) / 12
⇒ 4/12
⇒ 1/3 hours

Answer:
a=19, b=4, c=22
Step-by-step explanation:
The perimeter of a triangle is found by adding all 3 of the side together.
Side a + Side b + Side c = perimeter.
Use what they gave you for the 3 sides.
(2x + 5) + (x - 3) + (3x + 1) = 45 inches
Now just start simplifying the equation. You can start by adding the whole numbers 5 - 3 + 1 = 3
2x + x + 3x + 3 = 45
Now add the others.
2x + x + 3x = 6x so you have 6x + 3 = 45
Subtract 3 from both sides of the equation
6x = 42
Divide each side by 6
x = 7
So now plug the value of X into the equations your were give for all 3 sides.
Side a = (2x+5) or (2)(7) + 5 = 19
Side b = (x - 3) or (7 - 3) = 4
Side c = (3x + 1) or (3)(7) + 1 = 22
Check you answers by adding the 3 numbers. 19 + 4 + 22 = 45 inches
