Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the statement:
''Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number''.
Let us break down the statement into an algebraic expression.
First Portion:
Let the number be: n
The difference of a number n and 2: n -2
Twice the difference of a number n and 2: 2(n-2)
Twice the difference of a number and 2 is added to 6 = 2(n-2) + 6
Second Portion:
3 times the number n: 3n
4 more than 3 times the number: 3n + 4
Combine the First portion and Second Portion:
Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number:
2(n - 2) + 6 = 3n + 4
Therefore, the required algebraic expression is:
2(n - 2) + 6 = 3n + 4BONUS SOLUTION to determine the number n
Let us solve the expression
2(n - 2) + 6 = 3n + 4
2n - 4 + 6 = 3n + 4
flip the equation
3n + 4 = 2n - 4 + 6
3n + 4 = 2n + 2
3n - 2n = 2 - 4
n = -2
Thus, the value of n = -2

a bus accelerates from 2 m/s to 10 m/s in 5 seconds. What was its average acceleration?
Please Help
Answers
Answer:
I believe the answer is 4. Please correct me if I’m wrong.
Step-by-step explanation:
================================================
Work Shown:
A = old velocity = 2 m/s
B = new velocity = 10 m/s
C = change in time = 5 seconds
D = average acceleration
D = (change in velocity)/(change in time)
D = (B-A)/C
D = (10-2)/5
D = 8/5
D = 1.6 m/s^2
The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.

Which of the following statements are true about inverse matrices?
All square matrices have inverses.
If A and B are inverse matrices, then A and B must be square matrices.
The determinant of a singular matrix is equal to zero.
If A and B are inverse matrices, then A + B = I.
If A and B are inverse matrices, then det(A)xde(B)=0
Any zero matrix does not have an inverse.
If B = A–1, then A = B–1.
Answers
B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.
what is matrix ?An arrangement of integers in both columns and rows is known as a matrix. learns about matrices' components and dimensions and first presents them. A matrix is a rectangular grid with integers arranged in rows and columns.
The statements that are true about inverse matrices are:
Not all square matrices have inverses. A square matrix only has an inverse if its determinant is not equal to zero. If the determinant of a square matrix is zero, it is called a singular matrix and does not have an inverse.
If A and B are inverse matrices, then A and B must be square matrices. This is because only square matrices can have inverses.
The determinant of a singular matrix is equal to zero. This is because the determinant of a matrix is related to the linear independence of its columns or rows. A singular matrix has linearly dependent columns or rows, which means its determinant is zero.
If A and B are inverse matrices, then A + B = I. This is not necessarily true. In general, the sum of two inverse matrices is not necessarily the identity matrix.
If A and B are inverse matrices, then det(A) x det(B) = 1. This statement is almost true, but the correct statement is det(A) x det(B) = det(AB) = 1.
Any zero matrix does not have an inverse. This is because the determinant of a zero matrix is zero, and therefore it is singular and does not have an inverse.
If B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.

(0.85). 32 represents the final price of the cake in dollars because...
Answers
Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.
Step-by-step explanation:
1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.
2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
