Answer:

Hello,

What is tan 30°?

tan(30^o)=\dfrac {\sqrt{3} }{3}

Step-by-step explanation:

sin(30^o)=\dfrac{1}{2} \\\\cos(30^o)=\dfrac{\sqrt{3} }{2} \\\\\\tan(30^o)=\dfrac{sin(30^o)}{cos(30^o)} \\tan(30^o)=\dfrac{\dfrac{1}{2} }  { \dfrac{\sqrt{3} }{2} }\\\\ =\dfrac {1*2}{2*\sqrt{3} }\\\\ =\dfrac {\sqrt{3} }{3}

use the elimination method to solve the system of equations choose the correct ordered pair 7x+4y=39 2y+4y=14
Anvisha [2.4K]

x = 5 \: and \: y = 1.

Step-by-step explanation:

7x + 4y = 39 \:  -  {eq}^{n} (1)

2x + 4y = 14  \: \:  -  {eq}^{n} (2)

Multiply Equation no (1) with 2 and Equation no (2) with 7.

14 x + 8y = 78.

14x + 28y = 98.

( - ) \: \:  \:  ( - ) \:  \:  \: ( - )

0x +  -20y =  - 20

- 20y =  - 20

y =  \frac{ - 20}{ - 20}

y = 1

Substitute the value of "y" in Equation no (1)

7x + 4y = 39.

7x + 4(1) = 39.

7x + 4 = 39.

7x = 39 - 4

7x = 35.

x =  \frac{35}{7}

x = 5.

Given that R = 3x + 9y
Bingel [31]

Answer:

Step-by-step explanation:

R = 3x + 9y

They told us that R = 7, y = 6

So you can rewrite the equation as:

R = 3x + 9y

7 = 3x + 9(6)

7 = 3x + 54

Subtract 54 from both sides.

7 - 54 = 3x

-47 = 3x

To find x, you need to divide both sides by 3

3x = -47

x = -47/3
