Answer:

-10 because you do parenthesis first

Answer:

x = -10

Step-by-step explanation:

3(-2x - 3) + 4x - 3 = 8

~Simplify

-6x - 9 + 4x - 3 = 8

-2x - 12 = 8

~Add 12 to both sides

-2x = 20

~Divide -2 to both sides

x = -10

Write expression as a sine or cosine of an angle.
cos 94° cos 18° + sin 94° sin 18° ​

Answers

Answer:  cos(76)

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

Explanation:

The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:

cos(A - B) = cos(A)cos(B) + sin(A)sin(B)

cos(A)cos(B) + sin(A)sin(B) = cos(A - B)

cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)

cos(94)cos(18) + sin(94)sin(18) = cos(76)

----------

We can verify this by use of a calculator. Make sure your calculator is in degree mode.

cos(94)cos(18) + sin(94)sin(18) = 0.24192cos(76) = 0.24192

Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.

-3/7(21x+7)=-7x+11
A.) x=-7/8
B.) x=-7
C.) x=7
D.) x=-7/8

Answers

Answer:

B

Step-by-step explanation:

-3/7 (21x + 7) = -7x + 11

Let's simplify the left side real quick

Distribute the -3/7

(-3/7)21x + 7(-3/7)

-63x/7 + -21/7

-9x - 3 = -7x + 11

Move like terms to one side

Let's move the variables to the left side by adding both sides by 7x

-9x - 3 = -7x + 11

+7x        +7x

-2x - 3 = 11

Add both sides by 3

-2x - 3 = 11

     +3    +3

-2x = 14

Divide both sides by the coefficient, -2, to isolate the variable, x

-2x/-2 = 14/-2

x = -7

The new bookcase for your future dorm room has the dimensions of 24 in wide by 12 in deep by 36 in tall. If one average textbook has the dimensions of 8.5 in wide by 11 in long by 1.5 in tall, how many books could you fit on your bookshelf with no shelving?

Answers

Answer:

About 73.93 books. Round that to 73 books, because you can't place 93% of a book.

Step-by-step explanation:

You first calculate to dimensions of the bookcase, then you calculate the dimensions of the books. As a result, divide the calculation of the bookshelf by the calculation of the books, and you should have your answer.

Answers

Answer: Ray AC is correct

This is because ray AE points in the same direction along ray AC. Put another way, points C and E are on the same line as A. So relabeling from "ray AE" to "ray AC" does not change the ray itself.

Keep in mind that order is important. So saying "ray AE" is completely different from "ray EA" due to the fact that the first letter is the endpoint while the second letter is where the ray goes on forever. So we can think of starting at point A and going in the direction of E to get ray AE, or going in the direction of C to get ray AC, and we're talking about the same ray.

This is interesting. You cannot turn 1/4 or 2/4 or 3/4 into a mixed number because they are proper fractions. Perhaps ask your teacher about it? Or just rewrite the fractions as is and state they are in proper form.

Answer:

  (x, y, z) = (2, 2, -1/2)

Step-by-step explanation:

Most manual solutions to a system of 3 equations in 3 unknowns are ad hoc. The idea is to take advantage of any relationships that might exist between the coefficients.

Multiply the first equation by 2, then subtract the third equation.

  2(2x -y -4z) -(x -2y) = 2(4) -(-2)

  4x -2y -8z -x +2y = 8 +2 . . . . . . . eliminate parentheses

  3x -8z = 10 . . . . . simplify

Now, we can subtract this from the second equation:

  (3x -2z) -(3x -8z) = (7) -(10)

  6z = -3 . . . . . . . simplify

  z = -1/2 . . . . . . . divide by 6

Using the second equation, we can find x:

  3x -2(-1/2) = 7

  3x = 6 . . . . . . . . subtract 1

  x = 2 . . . . . . . . . divide by 3

Using the last equation, we can find y:

  2 -2y = -2

  1 -y = -1 . . . . . . divide by 2

  y = 2 . . . . . . . . add y+1

The solution is ...

  (x, y, z) = (2, 2, -1/2)

here from right to left we add a single number and write it under the line, if the sum is above 1 decimal value the value upto 1 decimal from the very right of that number is written , for example in case of 9+8 that would be 17 so we would write 7 and carry 1, and the oposite of that for subtraction

Just in the same way lets consider the following example
