Answer:

X = 14

Step-by-step explanation:

3(2x+6) = 2(4x-5)

you will need to multiply the outside number to the numbers in the parentheses so now it's: ( I reordered the terms to give you a heads up)

6x + 18 = 8x - 10

Reordered:

18 + 6x = -10 + 8x

Now let's solve for X

18 + 6x = -10 + 8x

Now combine like terms

18 + -2x = -10

Now subtract 18 to get -2x alone

18 + -2x = -10

-18 -18

Now it's:

-2x = -28

Now divide by -2 to get x alone

-2x = -28

/-2 /-2

And now it's:

X = 14

Answer:

x = 14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Subtract 8x from both sides.

Step 3: Subtract 18 from both sides.

Step 4: Divide both sides by -2.

In the accompanying diagram of right triangle ABC, the hypotenuse if AB, AC = 3, BC = 4, and AB = 5. Sin B is equal to

Trava [24]

Answer: $sin(B)=\frac{3}{5}$

Step-by-step explanation:

We are given that a triangle ABC is a Right Angled Triangle. The side AB is hypotenuse, so the angle opposite to side AB which will be angle C is a Right Angle (measures 90 degrees)

We have the side length of all 3 sides. Based on this information, we can construct a triangle with given measures. The triangle is shown in the attached image.

We have to find the value of Sin(B). Sin of an angle is defined as:

$sin(\theta)=\frac{\text{Opposite Side}}{\text{Hypotenuse}}$
