Answer:

subtract 2a + 3b - 3b =5 - 3b

simply 2a = 5 -3b

divide both sides by 2 . 2a over 2 = 5 over 2 - 3b over 2

simply a= 5- 3b over 2

Answer:

23.6°

Step-by-step explanation:

In this question we have to use some trigonometry to work out angle XVW. Since we are working out angles all of the trigonometric functions will have to be to the ⁻¹. The first thing we need to identify is will formula will we use out of the following:

Sin⁻¹ = Opposite ÷ Hypotenuse

Tan⁻¹ = Opposite ÷ Adjacent

Cos⁻¹ = Adjacent ÷ Hypotenuse

-------------------------------------------------------------------------------------------------------

10 = Hypotenuse

4 = Opposite

-------------------------------------------------------------------------------------------------------

We know which formula to use because the length won't be in the triangle for example we will be using the Sin triangle because we don't have an adjacent. If we don't have an adjacent then the other formula's won't work.

Now we substitute in the values to find the value of angle XVW

Sin⁻¹ = Opposite ÷ Hypotenuse

Sin⁻¹ = 4 ÷ 10

The value of angle XVW is 23.57817848

An equation is shown below: 3(4x − 2) = 1 Which of the following correctly shows the first two steps to solve this equation?
Svetlanka [38]

Answer:

3(4x − 2) = 1

4x − 2 = 1/3

4x = 1/3 + 2

4x = 1/3 + 6/3

4x = 7/3

x = 7/12
