Answer:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
Step-by-step explanation:
Given
Required
What does 9m + 3(1.2m) represent
The expression can be split to:
9m and 3(1.2m)
<u>For 9m:</u>
From the question, we understand that:
Multiply both sides by 9
This means that:
9m = the cost of lessons for 9 hours on weekdays
<u>For 3(1.2m):</u>
From the question, we understand that:
Multiply both sides by 3
This means that:
3(1.2m) = the cost of lessons for 3 hours on weekends
Hence, the expression represents:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
It's a bit of both, actually.
9 ≥ n actually states that the quantity 9 is either greater than or equal to the value of the variable n.
Depending on how exact you mean, it's true and false, because 9 ≥ n technically includes 9 is more than a number, but it also could be 9 is equal to a number.
I'd say the answer is probably true, but it's a bit confusing.
2.34 because 23.47 times .10 which is 10% of the tip would be 2.34
The details of the packages are not posted, however I can tell you how to find the answer.
First determine how many pencils are in each pack.
Then divide the price of the pack by the number of pencils to find out which pack has the least cost per pencil. To put this in equation form:
Whichever pack has the least cost per pencil is the one that is the best priced.
The quadrant would be the first one, because once reflected over the y-axis, it would become (2,-8), and once reflected over the x-axis, it would become (2,8)
