Ren was trying to solve a system of linear equations. He correctly argued that he could replace one equation by the sum of that equation and a multiple of the other. H
produce a system that has the same solution as the original system.
To show this, Ren wrote down a system of equations. He then determined which other systems of equations would have the same solution as his original system. Rem

Answer: Can't be simplified

Answer:

t=2

Step-by-step explanation:

Literally just move all the common like terms onto one side.

6=3t

It is usually prefered to have the variables on the left and the coefficients on the right so you would flip your equation.

3t=6

Then you get t by itself by dividing by 3. Your final answer should be 2.

Answer:

x = -6, 2

Step-by-step explanation:

A zero is the x-value of a point on the x-axis that the graph intersects. Knowing this, we can set the function itself to 0 to find the zeros.

1) Set the function to 0.

[tex]x^2+4x-12 = 0[/tex]

2) Factor out the polynomial. Ask yourself, what are two numbers that have a product of -12 and add up to 4? (In this case, it's 6 and -2.)

[tex]x^2+4x-12 = 0\\(x+6)(x-2) = 0[/tex]

3) Look at the answer from the last step. What do the x's have to equal in order for equation to equal 0? They have to be -6 and 2. Therefore, those are the zeros.

Answer:

135°

Step-by-step explanation:

The sum of interior angles in this rectangle is equal to 720

Two of the angles are right (has 90°)

so 4x + 180 = 720 subtract 180 from both sides

4x = 540 divide both sides by 4

x = 135°

Yes

Answer:

160 degrees

Step-by-step explanation:

That is a straight line, meaning that the sum of a and 20 has to equal 180.

a + 20 = 180

a = 180-20

a = 160

Answer:

28b2+12b

Step-by-step explanation:

The actual distance between the two cities is 96 miles.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that the map shows that 16 miles are represented by 0.5 inches.

Let x miles would be the actual distance between the two cities

When they are 3 inches apart on the map

According to the given situation, we can write the ratio would be as:

16 miles : 0.5 inches = x miles : 3 inches

⇒ 16/0.5 = x/3

Apply the cross-multiplication operation,

⇒ 0.5x = 48

⇒ x = 48/0.5

⇒ x = 96

Therefore, the actual distance between the two cities is 96 miles.

Answer:

7x+3y2-4x

Step-by-step explanation:

The value of the difference of the polynomials are,

⇒ 7x² + 3y² - 4x

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

The expression is,

⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)

Now, We can subtract the expression as;

⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)

⇒ 12x² - 11y² - 13x - 5x² + 14y² + 9x

⇒ 12x² - 5x² - 11y² + 14y² - 13x + 9x

⇒ 7x² + 3y² - 4x

Thus, The value of the difference of the polynomials are,

⇒ 7x² + 3y² - 4x

Answer:

Step-by-step explanation:

1) Number of white chocolate bars = x

Number of dark chocolate bars = y

Total bars = 15

x + y = 15 --------------(I)

Total cost = Php. 340

20x + 25y = 340 ----------------(II)

2)  We can use elimination method to solve this equations.

Multiply equation (I) by (-20) and then add the equations.

(I)* (-20)          -20x  -20y = - 300

(II)                    20x + 25y = 340     {Now add and x will be eliminated}

                                  5y = 40

                                    y = 40/5

y = 8

Substitute y = 8 in equation (I)

x + 8 = 15

      x = 15 - 8

x = 7

3) Number of dark chocolate bars = 8
