Answer:
23 students
Step-by-step explanation:
We assume the wording "when 5 rows of seats are filled, 2 seats remain empty" means that there are 2 empty seats in the 5th row (which then would <u>not</u> be filled).
If n is the number of seats in a row, we think the problem statement means ...
5n -2 = 4n +3
n = 5 . . . . . . . . . . add 2-4n
Then 5(5)-2 = 23 = 4(5) +3.
There are 23 students in the class.
Answer:
The answer is 16.8%
Step-by-step explanation:
First, find the difference in the price, which is $78. You can then use that number to find the percentage by dividing the difference by the original price, then moving the decimal over to the right twice. You prove this with the discount equation. $387= $465-(16.8%*465). You will get a number similar to 387, but that is only because you are using a rounded percentage.

Answer:
Step-by-step explanation:
If both base angles are equal and 44 is one of them, then the other one is also 44. The top angle is 180 - 88 = 92
If the top angle is 44 then the two base angles are
180 - 44 = 136
Since the base angles are equal, then each of them is 136/2 = 68
Answer:
Tina earned $11.5
Step-by-step explanation:
From the question, we are told that Tiana earns 2.50 less than twice what is earned by Add
let us have x as what is earned by Add
Thus, we have what is earned as 2x-2.5
Now Add, earned 6.50, so we want to know what Tina earned
That would be;
2(6.5) - 2.5
= 13-2.5
= 10.5
