What is the elimination method in math?

Answers

Answer 1

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Adele believes that 0.462 is written as "four tenths, sixty-two hundredths." Is she correct? Explain your answer. *


Answers

Answer:

Adele is not correct.

Step-by-step explanation:

The statement in itself wields an incorrect answer. However, when she states "sixty-two hundredths" it is further proven incorrect. This is because the 0.062 part of the total 0.462 would be pronounced as 62 thousandths.

Therefore, Adele is incorrect. The correct answer, however, would be: "Zero and four-hundred sixty-two thousandths."

The measures of two angles of a triangle are given. Find the measure of the third angle.
147° 12′, 30° 19′
51° 20′ 14″, 106° 10′ 12″

Example: Applying the Angle Sum of a Triangle Property
The measures of two of the angles of a triangle are 48° and 61°. See Figure 17.
Find the measure of the third angle, x.
SOLUTION 48° + 61° + x = 180° The sum of the angles is 180°.
109° + x = 180° Add.
x = 71° Subtract 109°.
The third angle of the triangle measures 71°.

Required

Find x

To do this, we simply apply sin formula which is:

[tex]sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

In this case, it is:

[tex]sin(x) = \frac{8}{14}[/tex]

[tex]sin(x) =0.5714[/tex]

Take arcsin of both sides

[tex]x = sin^{-1}(0.5714)[/tex]
