A ticket brokering company is randomly distributing tickets to customers who pre-ordered tickets for an upcoming concert. Out of

bonufazy [111]

Answer:

<em><u>12 tickets</u></em>

Explanation:

You must assume that the ratio of the number of tickets in row 7 is a constant.

That permits you to set a proportion with the ratio of the number of tickets in row 7 for the first batch of tickets and the ratio of the number of tickets in row 7 for the next 33 tickets sent out:

<u>1. Ratio of number of tickets in row 7 for the first batch.</u>

Number of tickets in row 7: 20
Total number of tickets: 20 + 19 + 16 = 55
Ratio: 20/55

<u>2. Ratio of number of tickets in row 7 in the next 33 tickets sent out:</u>

Number of tickets in row 7: x
Total number of tickets sent out: 33
Ratio: x/33

<u>3. Proportion</u>

Set the proportion and solve for x:

$\dfrac{20}{55}=\dfrac{x}{33}\\\\\\20\times 33=55x\\\\\\ x=\dfrac{20\times 33}{55}\\ \\ \\ x=\dfrac{20\times 3}{5}\\ \\ \\ x=4\times 3\\ \\ \\ x=12$

Answer: 12 tickets

3x(x + 6) = -10

emmasim [6.3K]

Answer:

Step-by-step explanation:

Expand it: $3x^2 + 18x = -10$

Add 10 to both sides: $3x^2 + 18x + 10 = 0$

Divide both sides by 3: $x^2 + 6x + \frac{10}{3} = 0$

Find <em>a</em>, <em>b</em> for $(x + a)^2 + b = x^2 + 2x + a^2 + b \overset{!}{=} x^2 + 6x + \frac{10}{3}$

It’s $a = \frac{6}{2} = 3 \land b = \frac{10}{3} - a^2 = 3 + \frac{1}{3} - 9 = -6 + \frac{1}{3}$

So, inserting it leads to: $(x+3)^2 -6 + \frac{1}{3} = 0$

Subtract <em>b</em> from both sides: $(x+3)^2 = 6-\frac{1}{3}$

Apply square root to both sides and consider the two solutions: $x + 3 = \pm\sqrt{6-\frac{1}{3}}$

Subtract 3 from both sides and you get $x = -3 \pm \sqrt{6 - \frac{1}{3}}$
