Answer: x=8

Step-by-step explanation: 12x > 9(2x-3)-21

12x > 18x-27-21

12x > 18x - 48

48 > 18x - 12x

48 > 6x

8 > x

Answer:

The correct answer is x = 8

Step-by-step explanation:

12x > 9(2x-3)-21

First start with parenthesis

12x > 18x - 27 - 21

-27-21  = -48

12x > 18x - 48

Now move the x value to the opposite side and switch the sign

12x - 18x > -48

Combine like terms

-6x > -48

Divide -48 by 6

x = 8

Use the properties of 30-60-90 and 45-45-90 triangles to solve for x in each of the problems below. Then decode the secret messa
Zarrin [17]

The trigonometric function gives the ratio of different sides of a right-angle triangle. The given problems can be solved as given below.

<h3>What are Trigonometric functions?</h3>

The trigonometric function gives the ratio of different sides of a right-angle triangle.

\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

1st.) x = 5 /Sin(30°)

x = 10

!) sin(45°) = 4/x

x = 4/sin(45°)

x = 4√2

I) Cos(45°) = √3 / x

x = √3 / Cos(45°)

x = √6

E) Tan(60°) = 3√3 / x

x = 3√3 / 3

W) For isosceles right-triangle, the angle made by the legs and the hypotenuse is always 45°.

x = 45°

N) x² + x² = (7√2)²

x = 7

V) Tan(60°) = 7 / x

x = 7√3/3

K) x² + x² = (9)²

x = 9/√2

Y) Sin(60°) = 7√3/x

x = 14

M) Sin(30°) = x/11

x = 11/2

T) Sin(45°) = x/√10

x = √5

A) x + 2x + 90° = 180°

x = 30°

O) Sin(45°) = √2 / x

x = 2

R) Tan(30°) = x / 4

x = 4/√3 = 4√3 / 3

S) Sin(60°) = x / (10/3)

x = 5√3 / 3

Pleaseee help <br><br> 6(3 - 7x) = -192
scZoUnD [109]

Answer:

x = 5

Step-by-step explanation:

6(3 - 7x) = -192

Divide each side by 6

6/6(3 - 7x) = -192/6

3 - 7x = -32

Subtract 3 from each side

3-7x-3 = -32-3

-7x = -35

Divide each side by -7

-7x/-7 = -35/-7

x = 5
