Answer:

1. -12x - 9y - 6

2. -12x + 36

3. -240

4. -2

5. x = -57

6. x = -6

7. x = 48

8. x = 20

9. x = -288

10. n = 8

Step-by-step explanation:

-5x - 13 + 3y - 7x - 12y + 7

-12x - 13 + 3y - 12y + 7

-12x - 6 + 3y - 12y

-12x - 6 - 9y

-12x - 9y - 6

-3(4x - 12)

-3(4x) + (-3)(-12)

-12x + 36

6x - 282

6(7) - 282

42 - 282

-240

6x + 2(y + x)

6(-2) + 2(7 + (-2))

-12 + 2(7 - 2)

-12 + 2(5)

-12 + 10

-2

x - 23 = -80

+ 23 +23

x = -57

12x = -72

/12 /12

x = -6

x/4 = 12

* 4 * 4

x = 48

3x + 12 = 72

- 12 - 12

3x = 60

/3 /3

x = 20

x/4 - 8 = -80

+ 8 + 8

x/4 = -72

* 4 * 4

x = -288

10.

-4(1 - 5n) - 8n = 92

-4 + (-4)(-5n) - 8n = 92

-4 + 20n - 8n = 92

-4 + 12n = 92

12n - 4 = 92

+ 4 + 4

12n = 96

/12 /12

n = 8

I am an improper fraction whose numerator and denominator are made of odd digits only. In my simplest form, my representation as

ASHA 777 [7]

Answer:

The fraction is = $\frac{21}{9}$

Step-by-step explanation:

In simplest form the fraction is represented in mixed number as $2\frac{1}{3}$ .

The fraction form of the mixed number can be given as :

$2\frac{1}{3}=\frac{7}{3}$

Let the fraction be = $\frac{7x}{3x}$ [As multiplying same numbers to numerator and denominator does not affect the proportion.

Sum of numerator and denominator is = 30

This, can be represented as:

$7x+3x=30$

Solving for $x$ .

$10x=30$

Dividing both sides by 10.

$\frac{10x}{10}=\frac{30}{10}$

$x=3$

So, the fraction will be = $\frac{7\times 3}{3\times 3}$

⇒ $\frac{21}{9}$
