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:
B
Step-by-step explanation:
0.05(x + 8) + 0.10(x) = 2.50
dimes = x
nickels = x + 8
Therefore,
0.05(x + 8) + 0.10(x) = 2.50
0.05x + 0.40 + 0.10x = 2.50
0.15x = 2.10
x = 14
William has 14 dimes and 22 nickels in his pocket.
