<h3>What is Division?</h3>
It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Here, Time duration of each learner = 1 minutes 30 seconds
= 3/2 minutes.
Total number of learners = 15
Time taken by all the speech category = 15 X 3/2
= 45/2
= 22 minutes 30 seconds
Thus, It will take approx. 22 minutes and 30 seconds for the speeches.

Answer:
7.75 or 7 3/4
Step-by-step explanation:
Divide 27 1/8 by 3 1/2 to find the length, because Length x Width = Area
When you divide, you get 7.75
This is the length.
You can also convert it into fraction form and get 7 3/4
Lol what do I answer here
Answer:
x^2 + 5x - 84 = 0
x = 7
Step-by-step explanation:
let the sister's age = y
sister's age (y) = 5 + x equation 1
xy = 84 equation 2
Make y the subject of the formula in equation 2
y = 84/x
equate equation 1 and 2
84/x = 5 + x equation 3
Multiply equation 3 by x
84 = 5x + x^2
x^2 + 5x - 84 = 0
tjis can be solved using quadratic equation
x^2 -7x + 12x -84 = 0
x(x + 12) -7(x + 12)
x = 7 or - 12
age cant be negative so his age is 7
First, figure out how long it takes Francis to get one paycheck.
You do this by dividing the number of weeks by the number of paychecks.
12 ÷ 6 = 2
Now, you divide 52 weeks by the time it takes to get one paycheck.
52 ÷ 2 = 26
This means that Francis gets 26 paychecks in 52 weeks.
