Answer:
Time left for each question is less than 5.5 minutes
Step-by-step explanation:
Given that:
Raphael is trying to solve 5 math questions in less than 20 minutes.
3 questions have been completed which have taken 3 minutes each.
To find:
How much time is left with Raphael for each question so as to reach his goal.
Solution:
First of all, let us find the time that has been already consumed by Raphael in solving the 3 questions.
3
3 = 9 minutes
Time left = Total Time - Time already consumed
Time left = 20 - 9 = 11 minutes
Number of questions to be solved = Total questions - Questions solved
Number of questions to be solved = 5 - 3 = 2
Average time left for each question = Time left divided by Number of questions to be solved
Average time left for each question = 11
2 = 5.5 minutes
Therefore, time left for each question is less than 5.5 minutes.

Given:
Two expressions are
and
.
To find:
The property that allows to compute
as
.
Solution:
According to associative property of addition, if a, b and c are real numbers, then

Using the associative property of addition, we get
![\left[\left(-\dfrac{1}{5}\right)+\left(-\dfrac{3}{5}\right)\right]+\left(\dfrac{1}{7}\right)=\left(-\dfrac{1}{5}\right)+\left[\left(-\dfrac{3}{5}\right)+\left(\dfrac{1}{7}\right)\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cleft%28-%5Cdfrac%7B1%7D%7B5%7D%5Cright%29%2B%5Cleft%28-%5Cdfrac%7B3%7D%7B5%7D%5Cright%29%5Cright%5D%2B%5Cleft%28%5Cdfrac%7B1%7D%7B7%7D%5Cright%29%3D%5Cleft%28-%5Cdfrac%7B1%7D%7B5%7D%5Cright%29%2B%5Cleft%5B%5Cleft%28-%5Cdfrac%7B3%7D%7B5%7D%5Cright%29%2B%5Cleft%28%5Cdfrac%7B1%7D%7B7%7D%5Cright%29%5Cright%5D)
Therefore, the required property is associative property of addition.
