$x = 4.82$

Step-by-step explanation:

Given equation is:

6.2 ÷ (2x+1) = 2 1/3 ÷4

Applying the division operation

$\frac{6.2}{2x+1} = 2\frac{1}{3} * \frac{1}{4}\\\frac{6.2}{2x+1} = \frac{7}{3}*\frac{1}{4}\\\frac{6.2}{2x+1} =\frac{7}{12}\\$

Cross multiplication

$6.2(12) = 7(2x+1)\\14x+7 = 74.4\\14x = 74.4-7\\14x = 67.4$

Dividing both sides by 14

$\frac{14x}{14} = \frac{67.4}{14}\\x = 4.8142857....$

Rounding off to nearest hundredth

$x = 4.82$

Trigonometry

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Angle θ = 30°

Adjacent Leg = x

Hypotenuse = 8

Step 2: Solve for x

Substitute in variables [cosine]: $\displaystyle cos(30^\circ) = \frac{x}{8}$
[Multiplication Property of Equality] Isolate x: $\displaystyle 8cos(30^\circ) = x$
Rewrite: $\displaystyle x = 8cos(30^\circ)$
Evaluate: $\displaystyle x = 4\sqrt{3}$
