Well, first of all, you need to use the distributive property. So, you multiply each item in the parentheses by 2/7, so you get 4s/7 + 6/7. If you don't understand, please reply and I will try to explain better. Hope it helps!

What is the value of x in the figure?

<h3>Answer: x = 29</h3>

======================================================

Work Shown:

x+61 = 90

x+61-61 = 90-61

x = 29

------------

Explanation:

The first step is valid because the two angles x and 61 are complementary angles. They form a right angle or 90 degree angle.
In the second step, I subtracted 61 from both sides to undo the "+61".

Answer:

$\lim_{x \to \infty} \frac{2500+17(x-100)}{x}=17$

Explanation:

1) Charges are:

Flat fee: 500
First 100 tickets: 20(100) = 2000
Tickets over 100: 17 ( x - 100), where x is the number of tickets.

2) Total charges: 500 + 2000 + 17(x - 100) = 2500 + 17(x - 100)

3) Average cost per ticket = total charges / number of tickets

⇒ [2500 + 17(x - 100) ] / x

4) limit as the number of tickets, x, becomes very high ⇒ x → ∞

⇒ $\lim_{x \to \infty} \frac{2500+17(x-100)}{x}=17$

5) Here is the demostration of the value of that limit:

2500 / x + 17x / x - 1700/x = 0 + 17 + 0 = 17
