Find The Value Of X12x6x+28Your Answer

Answers

Answer 1

Step-by-step explanation:

Hey there!

By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.

So,

2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)

8x + 28°=180°

8x = 180° - 28°

8x = 152°

[tex]x = \frac{152}{8} [/tex]

X = 19°

Therefore, X = 19°.

Hope it helps...

Answer 2

Answer:

x=19

Step-by-step explanation:

These are same-side interior angles. The Same-Side Interior Angles Theorem states that if two parallel lines are cut by a transversal, then the same side interior angles are supplementary. This means that the sum of the two angles is equal to 180°.

2x+6x+28=180°

8x=180-28

8x=152

x=19

Answers

Answer:

D 17.43

Step-by-step explanation:

3.5 times 3.63 equals 12.67 and 2 1/3 times 2.04 equals 4.76.  When you add them together you get 17.43.

The exact change Rodney needs to take with him to the produce stand is 17.42 dollars.

What is unitary method?

A unitary method is a mathematical technique for obtaining the value of a single unit and then deriving the required units by multiplying it with the single unit.

The exact change Rodney needs to take with him to the produce stand is the price of 3.5 pounds of cherries which is (3.5×3.62) dollars = 12.67 dollars added to the price of 2.33 pounds of peaches which is (2.33×2.04) dollars = 4.75 dollars.

∴ The total amount is (12.67 + 4.75) dollars.

= 17.42 dollars.

If f(x)=x²+3x-2
find f(-2)

Answers

Answer:

f(- 2) = - 4

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = (- 2)² + 3(- 2) - 2 = 4 - 6 - 2 = - 4

Value of f(-2) is -4

Given that;

f(x) = x²+3x-2

Find;

Value of f(-2)

Computation:

Given that;

f(x) = x²+3x-2

By putting x = -2

f(-2) = (-2)² + 3(-2) - 2

f(-2) = 4 - 6 - 2

f(-2) = 4 - 8

f(-2) = -4

So, -4 is the correct answer to the given equation.

[tex]\huge\boxed{66.42 \textdegree}[/tex]

Step-by-step explanation:

In order to solve for this missing angle, we can use trigonometry.

With angle B, we only have two sides: the adjacent of the angle and the hypotenuse of the angle. The adjacent side is the one laying directly next to the angle that isn't the hypotenuse.

Using SOH CAH TOA, we can see that the correct trig function for this would be cos because of CAH (Cosine = Adjacent over Hypotenuse)

Since we know the length of the sides but we don't know the angle, we are going to use inverse trig.

The adjacent side over our hypotenuse will be [tex]\frac{2}{5}[/tex] since 2 is the length of the adjacent and 5 is the length of the hypotenuse.

We know have the equation [tex]cos^{-1}(B) = \frac{2}{5}[/tex].

We now find what [tex]\frac{2}{5}[/tex] is (0.4) and find the inverse cosine of it. We can do this by plugging it into a calculator.

When we do this, we get the number [tex]66.42182152[/tex] etc. Rounding to the nearest hundredth gets us 66.42.

Hope this helped!

Answers

Answer:

x = -8

Step-by-step explanation:

Step 1: Write equation

5x - 7(x + 1) = 9

Step 2: Solve for x

Distribute -7: 5x - 7x - 7 = 9Combine like terms: -2x - 7 = 9Add 7 to both sides: -2x = 16Divide both sides by -2: x = -8

Step 3: Check

Plug in x to verify it's a solution.

Answers

Answer:

k = 5

Step-by-step explanation:

4 - 5k = -21

Transpose and subtract 4 from both sides:

4 - 4 - 5k = -21 -4

-5k = -25

Divide both sides by -5

-5k/-5 = -25/-5

k = 5
