483.6 is what percent of 180

liraira [26]

Answer:

We assume, that the number 180 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 180, so we can write it down as 100%=180.

4. We know, that x% equals 483.6 of the output value, so we can write it down as x%=483.6.

5. Now we have two simple equations:

1) 100%=180

2) x%=483.6

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=180/483.6

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 483.6 is what percent of 180

100%/x%=180/483.6

(100/x)*x=(180/483.6)*x - we multiply both sides of the equation by x

100=0.37220843672457*x - we divide both sides of the equation by (0.37220843672457) to get x

100/0.37220843672457=x

268.66666666667=x

x=268.66666666667

now we have:

483.6 is 268.66666666667% of 180

The figure shows two intersecting lines and measures of the resulting angles write an equation to help you solve for x , then fi

ehidna [41]

Given:

Given that two lines are intersecting at the point.

The angles (3x - 8)° and (2x + 12)° are the angles formed by the intersection of the two lines.

We need to determine the equation to solve for x and the value of x.

Equation:

The two angles (3x - 8)° and (2x + 12)° are vertically opposite. Hence, the vertically opposite angles are always equal.

Hence, we have;

$3x-8=2x+12$

Hence, the equation is $3x-8=2x+12$

Value of x:

The value of x can be determined by solving the equation $3x-8=2x+12$

Thus, we have;

$3x-8=2x+12$

Subtracting both sides of the equation by 2x, we get;

$x-8=12$

Adding both sides of the equation by 8, we get;

$x=20$

Thus, the value of x is 20.

Hence, the equation and the value of x are $3 x-8=2 x+12 \ and\ x=20$

Thus, Option D is the correct answer.
