Answer: See explanation
Step-by-step explanation:
Number of tickets Elian won = e
Number of tickets Alberto won = A = e - 10
Therefore, Elian + Alberto ticket = 100
e + (e - 10) = 100
2e - 10 = 100
2e = 100 + 10
2e = 110.
e = 110/2
e = 55
Elina has 55 tickets
Alberto has 55-10 = 45 tickets

[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{x^2-10x+24}=\frac{-3}{x-6}[/tex]1. Factor the denominator.
[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.
[tex]\displaystyle \Big ( \frac{x-6}{x-6} \Big ) \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]3. Simplify.
[tex]\displaystyle \frac{2x^2-12x}{(x-4)(x-6)}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]4. Combine like terms.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6}[/tex]5. Multiply the right side of the equation by (x-4)/(x-4).
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6} \Big ( \frac{x-4}{x-4} \Big )[/tex]6. Simplify.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3x+12}{(x-6)(x-4)}[/tex]7. "Cancel" out the denominators because they are equivalent.
[tex]2x^2-14x+5=-3x+12[/tex]8. Set the equation equal to 0.
[tex]2x^2-11x-7=0[/tex]Quadratic formula:
[tex]\displaystyle x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]9. Factor using the quadratic formula.
[tex]\displaystyle x = \frac{-(-11)\pm \sqrt{(-11)^2-4(2)(-7)} }{2(2)}[/tex]10. Multiply and simplify.
[tex]\displaystyle x = \frac{11 \pm \sqrt{177} }{4}[/tex]11. Plug this into your calculator and solve for x.
[tex]x=6.07603367 \approx 6.08[/tex] [tex]x=-0.57603367 \approx -0.58[/tex]The correct answer is A. x = 6.08, x = -0.58.

Question 12 (1 point) Johnny says the sequence below is (A) Arithmetic because it has a common difference. He also says the first term is 100. (B) Do you agree? a 65 – 100n (A) Is it arithmetic? (B) is the first term 1007 if not what is the first term?
Answer:
The sequence is Arithmetic because it uses subtraction.
The first term is a(1) = 65 since it comes first in the formula.
Step-by-step explanation:
We are given the equation 65-100n. 65 is the first term since it comes first in the arithmetic formula and 100n is the common difference. So the correct answer should be an arithmetic sequence and 65 as the first term.

The properties of similar triangles.In Geometry, two (2) triangles are said to be similar when the ratio of their corresponding sides are equal and their corresponding angles are in congruence.
By applying the properties of similar triangles, we have this expression:
AB/DE = BC/CD
Substituting the given parameters into the expression, we have;
9/6 = 15/x.

If f(x) = 2x - 5 , Find f(3).
Substitute 3 for x then type your final answer.
Answer:
f(3) = 1
Step-by-step explanation:
To find f(3), plug in 3 as x and simplify the expression:
f(x) = 2x - 5
f(3) = 2(3) - 5
f(3) = 6 - 5
f(3) = 1
So, f(3) = 1

A car travels 54.9 miles in an hour. If the car continues at the same speed for 2 hours, how many miles will it travel?
Answer:
6588 miles
Step-by-step explanation:
Here's what you have to do: multiply. 54.9×120= 6588 (you multiply it by 120 because that's how long two hours is) so if he traveled in the same speed for two hours the car would have traveled 6588 miles
