The math I used is probably not the quickest way, but for me, the easiest.
25*5=125 25+20=45 45*7=315 125+315=440 25*4=100 440+100=540 5+7+4=16
B is your answer.

Step-by-step explanation:
There are 5 couples are sitting in the row
<h3>How many couples are sitting in the row?.</h3>
The given parameters are
Maximum = 6 couples
In the hall, we have the following arrangements
<u>First couple</u>
Right = 2 couples
Left = 1 couple
<u>Another couple</u>
Left = 3 couple
Right = 1 couples
The left of the other couple is the right of the first couple
So, we have the following arrangements:
<u>First couple (1)</u>
Right = 2 couples
Left = 1 couple
<u>Another couple</u>
Right = 1 couples
The total number of couples is
Total = 1 + 2 + 1 + 1
Evaluate the sum
Total = 5
Hence, there are 5 couples are sitting in the row

Answer:
Step-by-step explanation:
<em>Since equations are not listed, i will simply figure out the correct answer.</em>
<em />
Profit is Income MINUS Cost.
The cost is a fixed cost of 2,100 per month.
Also a variable cost of 70 per unit (x), if x units sold, then variable cost would be "70x"
Total Cost = 2100 + 70x
Now, the income is from sales of each unit. Each unit sells for $84 and if x units sold, company's income would be:
84x
So, profit will be:
Profit = Income - Cost
Profit = 84x - (2100 + 70x)
Profit = 84x - 2100 - 70x
Profit = 14x - 2100
We can write the equation as:
All the triangles have 180° total angle measurement.
First question:
114 + 37 + x = 180°
151 + x = 180
x = 180 - 151
x = 29°
Second question:
93 + 46 + x = 180
139 + x = 180
x = 180 - 139
x = 41°
