Answer:

x=11/4

Step-by-step explanation:

You want all of the x's on one side, so you can subtract 16x from both sides, so you get 16 = 4x+5. Then, you subtract 5 from both sides to get 4x = 11. Finally, you divide by 4 so you get x=11/4.

Answer:

x = 11/4

Step-by-step explanation:

to solve this question you will have to combine the variables and evaluate it.

16x+16= 20x +5

collecting the like terms

16 - 5 + 16x = 20x

16 - 5 = 20x - 16x

11 = 4x

divide both sides by the coefficient of x which is 4

11/4 = 4x/4

x = 11/4

to check if your answer is correct , put the value of x = 11/4 into the question and you will see that the left handside equals the right handside.

Alicia draws a diagram to represent two forces, F1 and F2, acting on a body. The angle between the directions of the forces is 5

Nastasia [14]

Refer to the diagram shown below.

When the two forces F₁ and F₂ are added vectorially, the resultant force is R.
The angle x = 180° - 50° = 130°.

From the Law of Cosines, obtain
R² = F₁² + F₂² - 2F₁F₂ cos(130°)
Note that 2 cos(130°) = -1.2856.

Answer:
R = √(F₁²+ F₂² + 1.2856 F₁F₂ )
