Find the value of x and y

1 answer:

1) 180° - 146° = 34
9х - 2 = 34
9х = 34 + 2
9х = 36
х = 36 : 9
х = 4
-------------

2) (9х - 2) + (6у + 44) = 180°
(9 * 4 - 2) + (6у + 44) = 180
(36 - 2) + (6у + 44) = 180
34 + 6у + 44 = 180
6у = 180 - 34 - 44
6у = 102
у = 102 : 6
у = 17
---------------

Step-by-step explanation:

$\tt{ \frac{x}{2} - \frac{x}{5} = 2}$

Take the L.C.M of 2 & 5. It's ' 10 '. Firstly find out the factors of 2 [ i.e 1 × 2 ] and then secondly find out the factors of 5 [ i.e 1 × 5 ]. Now , Note that while finding L.C.M of any numbers, Common numbers & Remaining numbers must be multiplied. In our case , common number = 1 & Remaining numbers are 2 & 5. Multiply them : [ 1 × 2 × 5 = 10 ].

⟶ $\tt{ \frac{x \times 5 - x \times 2}{10} = 2}$

⟶ $\tt{ \frac{5x - 2x}{10} = 2}$

Subtract 2x from 5x :

⟶ $\tt{ \frac{3x}{10} = 2}$

Apply cross product property :

⟶ $\tt{3x \times 1 = 2 \times 10}$

⟶ $\tt{3x = 20}$

Here, We have to think about how to remove the coefficient 3. For that , Divide both sides of the equation by 3.

⟶ $\tt{ \frac{3x}{3} = \frac{20}{3}}$

⟶ $\tt{x =6.67}$

$\pink {\boxed{ \boxed{ \tt{⇾ Our \: final \: answer : \boxed{ \underline{ \tt{x = \frac{20}{3} \: or \: 6.67 }}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Can you please tell the real number?

by the way, it can be written in various ways:

= 56.987 × 10⁵

= 5.6787 × 10⁶

= .5687 × 10⁷

It may vary.. depending on the question and value asked

2a+b=5 and 6y+4y=48 show that 20a+10b has a greater value than 3x+2y

matrenka [14]

Answer:

Step-by-step explanation:

There is an error in the question. 6x+4y = 48

Multiply first equation by 10:

20x+10y = 50

Divide second equation by 2:

3x+2y = 24

50>24, so 20x+10y > 3x+2y
