4. The first two numbers in a sequence are 3, 9.
a. If this is an arithmetic sequence, what are the next 2 terms?

Answers

Answer 1

Answer:

15 & 21

Step-by-step explanation:

If this is an AP, the common difference is:

9 - 3 = 6

The next two terms are:

9 + 6 = 1515 + 6 = 21
Answer 2

In the arithmetic sequence :

The next 2 term of the arithmetic sequence is:

15 , 21

A sequence in which the difference between all pairs of consecutive numbers is equal is called an arithmetic progression.

We have the following information available from the question is:

The first two numbers in a sequence are 3, 9.

We have to find the next 2 terms of the arithmetic sequence.

Now, According to the question:

The first two numbers in a sequence are 3, 9.

a1 = 3

d = 9 - 3 = 6

The next 2 term of the arithmetic sequence is:

9 + 6 = 15

15 + 6 = 21

∠A and \angle B∠B are complementary angles. If m\angle A=(7x+23)^{\circ}∠A=(7x+23)
∘
and m\angle B=(5x+19)^{\circ}∠B=(5x+19)
∘
, then find the measure of \angle B∠B.

Answers

Since there are complementary angles, the value of angle B is 39°.

Angle A = 7x + 23°

Angle B = 5x + 19°

It should be noted that the total angles in a complementary angle are equal to 90°.

Therefore, we need to add angle A and B together and then equate them to 90°. This will be:

7x + 23° + 5x + 19° = 90°

Collect like terms

12x + 42° = 90°

12x = 90° - 42°

12x = 48°

x = 48°/12

x = 4°

Angle A = 7x + 23° = 7(4) + 23° = 28° + 23° = 51°

Angle B = 5x + 19° = 5(4) + 19° = 20° + 19° = 39°

The value of angle B is 39°.

When solving a two step equation, how do we know which number is the constant?

Answers

For example the problem 2x + 5 = 21, the constant is the number without the variable, and the solution would be x = 8.

Airfare from Atlanta, GA to Nashville,TN was decreased from $250 to $180. By what percentage did the cost of the airfare change?

Answers

Answer:A decrease of 28%

Step-by-step explanation: the question says decreased so you can mark out A and B then 250-180 is 70, 70% of 250 is 28%

The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

As per the given question,

Initial price of Airfare = $250

Final price of Airfare = $180

The percentage = change/initial  ×  100

Percentage decrease = (250 - 180)/250  × 100

⇒ 0.28 × 100 = 28%

Hence "The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%".

Answer:

x = 9

Step-by-step explanation:

to find the value of x

11x - 11 = 110 (alternate exterior angles are equal)

Substitute

11x = 110 -11

11x = 99

x = 99 ÷ 11

x = 9

Answer:

x=11

Step-by-step explanation:

Because 110= 11x-11, you can use this equation to solve.

First, add 11 to both sides:

121=11x

Then divide by 11:

11=x ------> x=11
