If, 5x - 4 = 2x + 3, Find the value of (3x)

Answer»

Answer:

3x=7

Step-by-step explanation:

5x-2X=3+4(you take 2x on the other side so it BECOMES negative 2x and similarly four on other side becomes positive 4)

3x=7

x=7/3(this is to prove the VALUE is correct or not

3 (7/3)=7

7=7

therefore, 3x=7

3.

Factories 64-(a +12)^2What will be the process of this question?

Answer»

Answer:

64-(a^2+144+2×12×a)=0

64-a^2-144+24a=0

0=a^2-24a+144-64

0=a^2-24a+80

0=a^-20a-4a+80

0=a (a-20)-4 (a-20)

23.

The numerator of a fraction is 6 less thandenominator If 3 is added to the numeratorand I is subtracted from the denominator, thefraction is equal to 2/3 find the originalnumber

Answer»

Answer:

Hi ,

Let the denominator = x

Numerator = x - 6

ORIGINAL fraction = ( x - 6 ) / x ---( 1 )

According to the problem given,

( x - 6 + 3 ) / x = 2/3

( x - 3 ) / x = 2 / 3

3( x - 3 ) = 2x

3x - 9 = 2x

3x - 2x = 9

x = 9

Put x = 9 in equation ( 1 ),

Original fraction = ( x - 6 ) / x

= ( 9 - 6 ) / 9

= 3 / 9

I hope this HELPS you.

ANSWER:

Step-by-step explanation:

The formulas required for Trigonometry are :-

$\sf{ sin \theta = \dfrac{Height}{Hypotenuse}}$

$\sf{ cos \theta = \dfrac{Base}{Hypotenuse}}$

$\sf{ tan \theta = \dfrac{Height}{Base}}$

$\sf{ cot \theta = \dfrac{Base}{Height}}$

$\sf{ sec \theta = \dfrac{Hypotenuse}{Base}}$

$\sf{ cosec \theta = \dfrac{Hypotenuse}{Height}}$

From this, we can DERIVE RELATIONS as:-

$\sf{ sin \theta = \dfrac{1}{Cosec \theta}}$

$\sf{ cos \theta = \dfrac{1}{Sec \theta}}$

$\sf{ Tan \theta = \dfrac{1}{ Cot \theta}}$

$\sf{ cot \theta = \dfrac{1}{tan \theta}}$

$\sf{ sec \theta = \dfrac{1}{cos \theta}}$

$\sf{ cosec \theta = \dfrac{1}{Sin \theta}}$

SQUARING Identities :-

$\sf{ sin^2 \theta = 1 - cos^2 \theta}$

$\sf{ tan^2 \theta = sec^2 \theta - 1}$

$\sf{ cot^2 \theta = cosec^2 \theta - 1}$

External formulas:-

$\sf{ tan \theta = \dfrac{sin \theta}{cos \theta}}$

$\sf{ cot \theta = \dfrac{cos \theta}{sin \theta}}$
