Answer:

[tex]\frac{6}{5}[/tex]

Step-by-step explanation:

let the denominator of the original fraction be x, then

[tex]\frac{x-2}{x}[/tex] ← original fraction

Then

[tex]\frac{2(x-2)}{x+5}[/tex] ← new fraction

The product of original and reciprocal of new is

[tex]\frac{x-2}{x}[/tex] × [tex]\frac{x+5}{2(x-2)}[/tex] ← cancel (x - 2)

= [tex]\frac{x+5}{2x}[/tex] = [tex]\frac{1}{4}[/tex] ( cross- multiply )

4(x + 5) = 2x

4x + 20 = 2x ( subtract 2x from both sides )

2x + 20 = 0 ( subtract 20 from both sides )

2x = - 20 ( divide both sides by 2 )

x = - 10

Then original fraction

[tex]\frac{x-2}{x}[/tex] = [tex]\frac{-12}{-10}[/tex] = [tex]\frac{6}{5}[/tex]

Answer:

113

Step-by-step explanation:

53 is one of the angles in the triangle

Then put 60+53+y=180 you get y=67

x+y=180 you get x=113

Answer: The angle C measures 120 degrees.

Step-by-step explanation:

For a polygon of n side, the sum of internal angle, in degrees  is given by:

S = (n - 2) x 180

Parallelogram

4 sides, so

S = ( 4 - 2) * 180 = 360

Two pair of equal angles

B and D measure 60

A and C measure x. so

2ₓ + 2 * 60 = 360

2× = 240

× = 240/2

× = 120

The angle C measures 120 degrees

Hope this helps! :)

Answer:

11

Step-by-step explanation:

The number with the last value in this data set is 11. All the other numbers are greater than it in terms of numerical value. Imagine if all the numbers were represented through pennies. 11 would have the least amount of pennies.

Answer:

km per min

Step-by-step explanation:

6km ÷ 60 = 0.1

Bonolo ran 0.1 km per min

it takes 100 mins= 0.1×10

100 mins means 1 hour 40 min

Answer:  -10 also your welcome

Answer:7

Step-by-step explanation:

Answer:

[see below]

Step-by-step explanation:

[tex]\frac{7}{52}[/tex] is a proper fraction. Therefore, it cannot be written as a mixed number.

7 can go into 52 7 times with 3 'parts' remaining.

This means that 7 is the whole number and the fraction is 3/7.

[tex]\frac{52}{7}=7\frac{3}{7}[/tex]

Hope this helps.

Answer:

[tex]1 + \frac{3}{x} [/tex]

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

[tex] \frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x} [/tex]

2) use difference of squares: a² - b² = ( a + b ) (a - b).

[tex] \frac{(x + 3)(x - 3)}{ {x}^{2} - 3x} [/tex]

3) Factor out the common term x.

[tex] \frac{(x + 3)(x - 3)}{ x(x - 3)} [/tex]

4) Cancle out x - 3 .

[tex] \frac{x + 3}{x} [/tex]

5) Simplify.

[tex]1 + \frac{3}{x} [/tex]

Therefor, the answer is 1 + 3/x.

Answer:

1 + 3 ÷ x

Just doing my streak. All credit goes to the person who answered first

Answer:

Step-by-step explanation:

The point-slope form of the equation that describes the line with a slope of m and including the point (x₀, y₀) is: y - y₀ = m(x - x₀)

m = 6

(1, 10)  ⇒    x₀ = 1,  y₀ = 10

Therefore:

y - 10 = 6(x - 1)          ← the point-slope form

y - 10 = 6x - 6       {add 10 to both sides}

y = 6x + 4               ← the slope-intercept form

Answer:

8 units

Step-by-step explanation:

2(3x-3)=4x-1

6x-6=4x-1

2x=5

x=2.5

3x-3

3(2.5)-3

Answer:

11 miles an hour

Step-by-step explanation:

44 miles divided by 4 hours would equal 11 miles in one hour, meaning her average speed would be 11 miles an hour

Answer:

The average speed is 11

Step-by-step explanation:

You would have 44 on top and 4 on the bottom(44/4)

then you would divide the 4 by four and the 44 by four to get 11 miles an hour.

Answer: 1. x = 32, 2. x = 16, 3. x = 77

Step-by-step explanation: All of these angles are 90 degree angles, therefore by subtracting the known term from 90, you are able to find the value of x. I hope that this helps :)

Answer:

multiple but if that dont work ion know what to tell you

Answer:

Step-by-step explanation:

(2[tex]x^{2}[/tex]+3)(x+4)

2[tex]x^{3}[/tex]+8[tex]x^{2}[/tex]+3x+12

2 6/7 ÷ 2/3

= 20/7 ÷ 2/3

20/7 × 3/2

= 60/14

reduce to it's lowest term

30/7 = 4 2/7
