Answer:

x=-14

Step-by-step explanation:

The 2 angles are opposite of each other. This means that they are vertical angles, are they are congruent.

Since they are congruent, we can set them equal to each and solve for x.

9x+184=7x+156

To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

First, subtract 7x from both sides.

9x-7x+184=7x-7x+156

9x-7x+184=156

2x+184=156

Next, subtract 184 from both sides.

2x+184-184=156-184

2x=156-184

2x=-28

Finally, divide both sides by 2.

2x/2= -28/2

x=-28/2

x= -14

Average speed for a driving 330 miles in 5 1/2 hours

Nookie1986 [14]

Here are some examples of basic distance problems.

Example 1: “A man has to bicycle 30 miles. He will travel at 6 mph. How long will it take?”

The distance is 30 miles and the rate is 6 mph. We will plug these values into the formula, like so.

To solve it, we need to divide both sides by 6.

This means it will take 5 hours.

Example 2: “A bug travels at a rate equal to 3 inches per hour. How far will it travel in 4 hours?”

The rate is 3 inches/hour and the time is 4 hours. We will plug these values into the formula, like so.

To solve it, we need to simply multiply the values.

This means it will travel 12 inches.

Example 3: “An asteroid travels 300,000 miles in 4 hours. How fast was it traveling?”

The distance is 300,000 miles and the time is 4 hours. We will plug these values into the formula, like so.

To solve it, we need to divide both sides by 4.

This means it was traveling at 75,000 mph.

The Florida Tourist Commission selected a random sample of 200 people that attended one or more concerts during the first weeken

Alina [70]

Answer:

0.8 or 80%

Step-by-step explanation:

Let A and B be the events

A: “The concert goer went to Orlampa Skydome”

B: “The concert goer went to the Bithlo Megaplax”

Then the probability P(A) that a concert goer went to Orlampa Skydome is

P(A) = 120/200 = 0.6

Similarly,

P(B) = 100/200 = 0.5

We are looking for P(A∪B), the probability that a concert goer went to Orlampa Skydome OR the Bithlo Megaplax.

We know that

P(A∪B) = P(A) + P(B) - P(A∩B)

but P(A∩B) is the likelihood that a concert goer went to Orlampa Skydome AND the Bithlo Megaplax.

Since the events are independent,

P(A∩B) = P(A)P(B) = 0.6*0.5 = 0.3

and

P(A∪B) = 0.6 +0.5 - 0.3 = 0.8 or 80%

According to the synthetic division below, which of the following statements are true?

kykrilka [37]

Answer:

Options (A) and (D)

Step-by-step explanation:

We can write the given division as,

$\frac{2x^2+6x-8}{x+5}=2x-4+\frac{12}{x+5}$

Option (A)

When (2x² + 6x - 8) is divided (x + 5), the remainder is 12.

True.

Option (B)

When (2x² + 6x - 8) is divided (x - 5), the remainder is 12.

False.

Option (C)

When x = 5,

2x² + 6x - 8 = 12

2(5)² + 6(5) - 8 = 50 + 30 - 8

= 72

False.

Option (D)

When x = -5,

2(-5)² + 6(-5) - 8 = 50 - 30 - 8

= 12

True.

Option (E)

(x - 5) is a factor of 2x² + 6x - 8

If (x - 5) is a factor value of 2x² + 6x - 8 should be zero.

False.

Option (F)

(x + 5) is a factor of 2x² + 6x - 8

If (x + 5) is a factor then by substituting x = -5 in the expression value should be zero.

But the value is 12.

False.
