4x - 35 = 234

Solve for 'x'.

Answers

Answer:

X= 67.25

Step-by-step explanation:

4x-35=234

Add 35 to both sides

4x= 269

Divide both sides by 4

X= 67.25

Answer:

x = 67,25

Step-by-step explanation:

Here it is given that,

x is an unknown to know. Since we are intelligent students, we will bring the unknowns to the left limb, and the numbers known in the right limb.

[tex]\:[/tex]

We can write this matematically as,

[tex]\rightarrow 4x - 35 =234[/tex]

Move the constant to the right,

[tex]\rightarrow 4x =234 + 35[/tex]

Add the numbers,

[tex]\rightarrow 4x =269[/tex]

Divide both sides of the equation by 4,

[tex]\rightarrow x =\frac{269}{4}[/tex]

We determine the value of x,

[tex]\rightarrow \underline {x=67,25}[/tex]

The length of an arc AB from the given circle with radius 6in is 15.7in

Length of an arc

The formula for calculating the length of an arc is expressed as:

L = r theta

where

r is the radius = 6in

theta is the central angle = 150 degrees = 5/6π rad

Substitute

L = 6(5/6π)

L = 5π

L = 5(3.14)

L = 15.7in

Hence the length of an arc AB from the given circle with radius 6in is 15.7in
