So,the right answer is 3.

Hope it will help you
This is very basic, so it won't take long. First step in any algebraic question is to combine like terms, any term with alike variables or constants. So to begin with we need to combine the constants.
2n+1=7 To combine like terms, we need to move the 1 over to the seven by subtracting on both sides like a mirror.
2n+1-1=7-1
2n=6
Then, since it's 2n we need to divide by two to get n isolated.
2n/2=6/2
n=3
The final answer is n=3.

solve the following system x=3 y=3x-1
Answers
Answer:
x = 3
y = 8
Step-by-step explanation:
Since it gives you x, you need to plug in the number given for it into the equation:
y = 3x - 1
y = 3(3) - 1
y = 9 - 1
y = 8
So now you have, x = 3 and y = 8

In a rectangle ABCD the diagonals intersect each other at point O, E is a midpoint of the side AB , and m∠BAC = 50°. Find the measure of angle EOD.
Answers
Answer:
130°
Step-by-step explanation:
In the picture attached, the rectangle can be seen.
We know that m∠BAC = 50°, then m∠ADB is also 50°. m∠AOE must be 180° - 90° - 50° = 40°, and m∠OAD = 90° - 50° = 40°, then m∠DOA = 180° - 40° - 50° = 90°. Finally m∠EOD = m∠DOA + m∠AOE = 90° + 40° = 130°

Helps the first 2 questions
Answers
Answer:
The first one is 5m - 4y.
The second one is 3x - 4y.
Step-by-step explanation:
A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as x + 2x + 6 < 50, where x represents the smaller number. From the set {13, 14, 15, 16, 17}, the values of x for which the inequality holds true are .
Answers
Answer:
First, you have to simplify the inequality and solve for x.
x + 2x + 6 < 50
3x + 6 < 50
3x < 44
x < 14 2/3
So, you now have another set of numbers, {13, 14, 15, 16, 17}, and you know x must be smaller than 14 2/3. The only two numbers in that set that works are 13 and 14, making A: {13, 14} the correct answer.

Twenty eight slips of paper are numbered 1 through 28 and are distributed among a group of people. A random number generator is used to select a single number between 1 and 28, inclusively
A fair decision is made using this process
How many people could be in this group?
A. 3
B. 6
C. 7
D. 12
Answers
Answer:
Option D, 7, is the right answer.
Step-by-step explanation:
It is given that 28 slips of papers are numbered through 1 to 28.
Accordingly, there are 28 numbers.
For a fair decision, the number of slips with each one must be the same.
Therefore, the decision will only be fair if the number of people in the group is a factor of 28.
The factors of 28 are - 1, 2, 4, 7, 14 and 28.
In this way, 7 is the only factor of 28 among the given options.
Hence, the answer will be 7.

Charles plots the point with the polar coordinates (−5,−3π/4). How does he plot this point?
Charles first determines which line the angle of rotation places the point on. This line tells Charles that the point must lie in _____ a if r is positive or ____ if r is negative.
The radius of 5 tells Charles that the point lies on the fifth circle of the polar plane. The value of r is negative. Therefore, the point will lie _____ the angle of rotation.
Answers
Answer:
This line tells Charles that the point must lie in Quadrant 3 if r is positive or Quadrant 1 if r is negative.
The value of r is negative. Therefore, the point will lie in the opposite quadrant as the angle of rotation.
Step-by-step explanation:
With polar coordinates the first value represents the distance from the origin and the second value represents the rotation from 0. In this case the distance from the origin value is negative, which means it will be in the opposite quadrant to the angle of rotation.
(-5, −3π/4) results in the same point as (5, π/4)
A rotation of −3π/4 results in the same rotation as 5π/4
The rotation results in Quadrant 3 but because the distance value is negative the final resulting point is in Quadrant 1.

An investing group has $50,000 to invest. They put the money in an account that has an annual interest rate of 6%, compounded monthly. How much money will the group have at the end of 10 years?
Answers
The investing group will have $90970 at the end of 10 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We can use the formula for compound interest to solve this problem:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
where A is the total amount,
P is the principal
r is the annual interest rate,
n is the number of times the interest is compounded per year, and
t is the number of years.
P = $50,000, r = 0.06, n = 12 and t = 10.
Substituting these values into the formula, we get:
A = 50000(1 + 0.06/12)¹²⁰
A = 50000(1.005)¹²⁰
A=$90970
Therefore, the investing group will have $90970 at the end of 10 years.

Given the initial value a0 = -5 and the general form of the sequence given as An = 3an-1 + 12
To get the first six terms of the sequence, we will substitute for n=1 up to n= 6 in the general equation.
