8. To calculate 159 - 73, a student writes the follow-

Evgen [1.6K]

The question is an illustration of solving equations using estimates.

The student's strategy makes sense because he uses estimation to solve the given equation

The correct sequence of equation is as follows:

$\mathbf{159 - 73}$

$\mathbf{159 - 73 =160 - 70- 1 - 3}$

$\mathbf{159 - 73 =90- 4}$

$\mathbf{159 - 73 =86}$

We have:

$\mathbf{159 - 73}$

Add 0 to the equation

$\mathbf{159 - 73 =159 + 0- 73}$

Express 0 as 1 - 1

$\mathbf{159 - 73 =159 + 1 - 1- 73}$

$\mathbf{159 - 73 =160 - 1- 73}$

Add another 0

$\mathbf{159 - 73 =160 - 1- 73 + 0}$

Express 0 as 3 - 3

$\mathbf{159 - 73 =160 - 1- 73 + 3 - 3}$

$\mathbf{159 - 73 =160 - 1- 70 - 3}$

Rewrite as:

$\mathbf{159 - 73 =160 - 70- 1 - 3}$

Solve

$\mathbf{159 - 73 =90- 4}$

$\mathbf{159 - 73 =86}$

In order to slove the following system of equations by addition, which of the following could you do before adding the equations

Vladimir [108]

Answer:

B. use multipliers -3 and 2

Step-by-step explanation:

If you're solving the system by "addition," multiplying the equations by the chosen numbers needs to result in opposite coefficients for one of the variables.

<h3>Effect of answer choices</h3>

A. The system becomes ...

12x -6y = 21
12x -12y = 60

No variable has opposite coefficients.

B. The system becomes ...

-12x +6y = -21
6x -6y = 30

The y-variable has opposite coefficients. This is a good choice.

C. The system becomes ...

12x -6y = 21
6x -6y = 30

No variable has opposite coefficients.

D. The system becomes ...

4/3x -2/3y = 7/3
3x -3y = 15

No variable has opposite coefficients.

Additional comment

The simplest "no brainer" solution is to use the coefficients of one of the variables, negating one of them. Multiply each equation by the opposite equation's coefficient. Here, the y-coefficients are -2 and -3, and the multipliers of answer choice B are -3 and 2, consistent with this advice. (The sign of 2 was changed.)

Answer:

see explanation

Step-by-step explanation:

(a)

The opposite sides of a rectangle are congruent, hence

x + 1 = 5 ( subtract 1 from both sides )

x = 4

x - 1 = 3 ( add 1 to both sides )

x = 4

(b)

The sum of the 3 angles in a triangle = 180°, hence

3y + 2y + y = 180

6y = 180 ( divide both sides by 6 )

y = 30
