Answer:

x = 20

Step-by-step explanation:

The 2 angles are vertical and congruent, thus

10x - 27 = 8x + 13 ( subtract 8x from both sides )

2x - 27 = 13 ( add 27 to both sides )

2x = 40 ( divide both sides by 2 )

x = 20

Answer:

(8x+13)=(10x-27) being vertically opposite triangles.

Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x

Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x

The total cost f(x), in dollars, for renting a vacation house for x days is shown:

MA_775_DIABLO [31]

Answer:

Option D.The number of dollars it costs to rent the house for 10 days

Step-by-step explanation:

we have

f(x) -----> the total cost for renting a vacation house

x ------> the number of days rented

we know that

f(x)=10+250x

For x=10 days

substitute in the function

f(10)=10+250(10)=$2,510

f(10) represent the number of dollars it costs to rent the house for 10 days

Which of the following correctly names a side of the triangle below?

slamgirl [31]

Answer:

C. $\frac{}{AB}$

Step-by-step explanation:

You can solve this in two ways, firstly by eliminating all the wrong answers, and secondly by just knowing that the horizontal line in $_$ $\frac{}{AB}$ means that we are talking about a line.

This is how we solve this question by using the eliminating process.

(A. ∠C) is not the right answer because the ∠ sign lets us know that this answer represents an angle, not a line

(B. B) is not the right answer because it represent a point, not a line (in math we use a singular capital letter to represent points)

(D. ΔABC) is not the right answer because the Δ sign lets us know that the answer represents a triangle, not a line.

Therefore, the only option left is C. $\frac{}{AB}$

3. Find the length of the missing side given the information below.

Lubov Fominskaja [6]

<h3>Answer: 12.5 (choice C)</h3>

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

We apply the pythagorean theorem to find this answer.

a = 11 and b = 6 are the given legs

c = unknown hypotenuse

So,

a^2+b^2 = c^2

c = sqrt( a^2+b^2 )

c = sqrt( 11^2 + 6^2 )

c = sqrt( 121 + 36 )

c = sqrt( 157 )

c = 12.52996 approximately

c = 12.5

Side note: once you replace 'a' and b with 11 and 6, you can compute everything with a calculator in one single step more or less. The steps above are shown if you wanted to find the exact value sqrt(157).

There were 724 zombies that attacked a player in Call of Duty. The player killed 65%. How many zombies did the player kill?

kvasek [131]

Answer:

470 zombies

Step-by-step explanation:

To find how many they killed, multiply 724 by 0.65

724(0.65)

= 470.6

Round down to 470, since there can only be a whole number for zombies

So, the player killed approximately 470 zombies
