If EF = 2x-7, FG = 4x-20, and EG = 21, find the values of x, EF, and FG.

Serggg [28]

Given -:

EF = 2X-7

FG = 4X-20

EG = 21

FIND OUT

EF =?

FG = ?

To proof

as given in the question

we have the value of EF = 2X-7 , FG = 4X-20 and EG = 21

Thus we have

EG = EF + FG

21 = 2X-7 + 4X- 20

21 = 6x - 27

48 = 6x

x = 8

Hence proved

Now put this value

$EF = 2\times 8 - 7\\EF = 9$

Now

$FG = 4\times 8 - 20\\FG = 12$

Hence proved

The sum of two numbers is 27. The larger number is 6 more than twice the smaller number. What are the numbers?

yawa3891 [41]

Answer:

Let the smaller number be x

Then the sum is

(6 + 2x) + x = 27

We now find for x

2x + x + 6 = 27

3x + 6 = 27

3x = 27-6

3x = 21

x = 21/3

x = 7

Therefore the smaller number is 7

The larger number is (2×7) + 6 = 20

Troyanec [42]

Answer:

$Area = 60x - x^2$

Step-by-step explanation:

Given

$Perimeter = 120$

$Side\ 1 = x$

Required

The area of the garden

First, we calculate the length of the other side using:

$Perimeter = 2 *(Side\ 1 + Side\ 2)$

This gives:

$120 = 2 *(x + Side\ 2)$

Divide both sides by 2

$60 = x + Side\ 2$

Make Side 2 the subject

$Side\ 2 = 60 - x$

So, the area of the garden is:

$Area = Side\ 1 * Side\ 2$

$Area = x * (60 - x)$

Expand

$Area = 60x - x^2$

The sides of a rectangle are in the ratio 2:5. The perimeter of the rectangle is 70 cm. What is the width of the rectangle?

EleoNora [17]

Width = 10cm

Length = 25cm

<u>Explanation: </u>

Given, width:length = 2:5

Let width = 2x ,

So, length = 5x

Perimeter of rectangle = 2x(length + width)

According to the question,

$70cm = 2X(5x + 2x)\\70cm = 2X(7x)\\35cm = 7x\\x = 5cm$

Hence,

Width = 10cm

Length = 25cm
