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:

Area of Figure 1 = 48

Step-by-step explanation:

We are given CD and EF. We can use this to find the scale factor between the two shapes.

The scale factor from Figure 1 to Figure 2 is 7/4.

The scale factor from Figure 2 to Figure 1 is 4/7.

Perimeter of Figure 2: 16 × 7/4 = 28cm, which is correct.

Area of Figure 1: 147 × (4/7)^2 = 48cm^2 We square the SF as we only worked out the Length Scale Factor. The Area Scale Factor is the Length Scale Factor squared.

I hope this helps!! ^-^

Answer:

48 cm² and 28 cm

Step-by-step explanation:

The ratio of the sides 1 : 2 = 4 : 7

The ratio of the sides 2 : 1 = 7 : 4

The ratio of perimeters is the same as ratio of sides

let the perimeter of 2 be x , then

[tex]\frac{16}{x}[/tex] = [tex]\frac{4}{7}[/tex] ( cross- multiply )

4x = 112 ( divide both sides by 4 )

x = 28

Perimeter of fig. 2 is 28 cm

-----------------------------------------------------

Given ratio of sides = a : b , then

ratio of areas = a² : b²

Here ratio of sides = 4 : 7

ratio of areas = 4² : 7² = 16 : 49

let x be the area of fig. 1 and using proportion

[tex]\frac{16}{x}[/tex] = [tex]\frac{49}{147}[/tex] ( cross- multiply )

49x = 2352 ( divide both sides by 49 )

x = 48

area of fig. 1 is 48 cm²

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:

  18 oz for $6.30

Step-by-step explanation:

The cost per ounce is found by dividing the cost by the number of ounces:

  $6.30/(18 oz) = $0.35/oz

  $4.56/(12 oz) = $0.38/oz

  $2.59/(7 oz) = $0.37/oz

The lowest cost per ounce is $0.35 per ounce for the 18-ounce package.

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

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]

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.

60° + x = 180°

x = 180° - 60°

x = 120°

Answer:

the sum of exterior angle of a polygon is always 360 degree.

therefore,

xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°

40x = 360°

x = 360/40 = 9

x = 9

The sum of the exterior angles of a polygon is 360 degrees, so the value of x is 9

The exterior angles of the polygon are given as:

xº, 2x°, 4x°, 6x°, 8x°, 9x°  and 10x°

The exterior angles of a polygon add up to 360 degrees.

So, we have:

[tex]x\º+ 2x\°+ 4x\°+ 6x\°+ 8x\°+ 9x\° +10x\° = 360\°[/tex]

Evaluate like terms

[tex]40x\° = 360\°[/tex]

Divide both sides of the equation by 40

[tex]x\° = \frac{360\°}{40}[/tex]

Divide 360 by 40

[tex]x\° = 9[/tex]

Rewrite as:

[tex]x = 9\°[/tex]

Hence, the value of x is 9
