Find The Value Of X A) 3B) 14C) 5D) 2

Answers

Answer 1

Answer:

C) 5

Step-by-step explanation:

The measure of angle TSU is 75°. (180° - 105° because it is a flat angle)

The sum of all the angles of a triangle is 180° as well.

You can write an equation to solve for x.

12x + 9x + 75 = 180

Isolate x.

12x + 9x = 180 - 75

12x + 9x = 105

Add the 12 and the 9.

21x = 105

Find what x is.

x = 105 ÷ 21

x = 5

A book sold 36,600 copies in its first month of release. Suppose this represents 7.1% of the number of copies sold to date. How many copies have been sold to date?

Answers

Answer:

515,493 copies sold

Step-by-step explanation:

Since this is a ratio problem and we have three values and one variable that we need to find (copies sold to date) then we can use the Rule of three to solve this problem. We simply need to multiply the diagonal values and divide by the third value to get the variable. This can be seen below...

36,600 copies   <=====>   7.1%

    x  copies   <========>  100%

(36,600 * 100) / 7.1 = 515,492.96  

Since the number of books cannot be a decimal we must round up to the nearest book sold, which would mean that the number of copies sold to date is 515,493 copies sold

The length of a side of a regular pentagon is f + 12.
Write the perimeter of the figure in one simplified
expression.

Answers

Answer:

5f+60

Step-by-step explanation:

Answer:

P = 5f + 60

Step-by-step explanation:

The Perimeter of a Regular Shape

A regular shape has sides that are all the same length as each other and angles that are all congruent to each other. The perimeter is the total distance around the outside of a shape.

To find the perimeter of a regular shape, we simply multiply one side length by the number of sides of the shape.

It's given the length of a side of a regular pentagon (n=5) as L=f+12.

The perimeter of the pentagon is 5 times f+12:

P = 5(f + 12)

Operating:

P = 5f + 60

What is the equivalent expression that represents its perimeter 80x-64 HELP!


1)80x-64

2) 8x

3) 10x-8

4)8(10x-8)

Answers

Answer:

4. 8(10x-8)

Step-by-step explanation:

An "equivalent expression" has the same value to that of the original expression.

8(10x-8) is an equivalent expression of 80x-64 because both have the same value.

Let's solve.

8(10x-8) = 80x-64

8x10x-(8x8) = 80x-64

80x-64 = 80x-64

This makes the answer correct.

Choice 1 is just the same expression, so it's not an equivalent expression.Choice 2 and 3 are not equivalent expressions as well.

how would the fraction 5÷1-√(3 be rewritten if it's denominator is rationalized using difference of squares

Answers

Answer:

-5(1 + √3)/2

Step-by-step explanation:

To rationalize 5÷1-√3, we multiply both the numerator and the denominator by the conjugate of 1 - √3 = 1 + √3.

So 5 ÷ (1 - √3) = 5/(1 - √3), we multiply by the conjugate of the denominator, we have

5/(1 - √3) × (1 + √3)/(1 + √3) = 5(1 + √3)/[(1 - √3) × (1 + √3)]

=  5(1 + √3)/(1² - (√3)²)

=  5(1 + √3)/(1 - 3)

= 5(1 + √3)/-2

= -5(1 + √3)/2

Find the inverse function.
8x – 4y = 24

Answers

Answer:

Simplifying
8x + -4y = 24

Solving
8x + -4y = 24

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.
8x + -4y + 4y = 24 + 4y

Combine like terms: -4y + 4y = 0
8x + 0 = 24 + 4y
8x = 24 + 4y

Divide each side by '8'.
x = 3 + 0.5y

Simplifying
x = 3 + 0.5y

If point P is Four-sevenths of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into? 4:1 4:3 4:7 4:10

Answers

Answer: Point P partitioned the line segment MN into 4:3.

Step-by-step explanation:

Point P is [tex]\dfrac47[/tex]of the distance from M to N.

Let the distance between M to N =x.

[tex]MP=\dfrac47x[/tex]

Point P partition the directed line segment from M to N .

MN = MP+PN

[tex]\Rightarrow\ x=\dfrac47 x+PN\\\\\Rightarrow\ PN =x-\dfrac47 x\\\\\Rightarrow\ PN=\dfrac37 x[/tex]

Ratio of MP to PN = [tex]=\dfrac{\dfrac{4}{7}x}{\dfrac{3}{7}x}=\dfrac43[/tex]

∴ Point P partitioned the line segment MN into 4:3.
