Answer:

x=−2

Step-by-step explanation:

1 Expand.

6-2x-12=3x+4

6−2x−12=3x+4

2 Simplify  6-2x-126−2x−12  to  -2x-6−2x−6.

-2x-6=3x+4

−2x−6=3x+4

3 Add 2x2x to both sides.

-6=3x+4+2x

−6=3x+4+2x

4 Simplify  3x+4+2x3x+4+2x  to  5x+45x+4.

-6=5x+4

−6=5x+4

5 Subtract 44 from both sides.

-6-4=5x

−6−4=5x

6 Simplify  -6-4−6−4  to  -10−10.

-10=5x

−10=5x

7 Divide both sides by 55.

-\frac{10}{5}=x

−

5

10

​

=x

8 Simplify  \frac{10}{5}

5

10

​

  to  22.

-2=x

−2=x

9 Switch sides.

x=-2

x=−2

Enter numbers to evaluate ‐13−23.
Nana76 [90]

Answer:

- 13 - 23 = - 13 + (-23)

= -36

- 13 - (- 23) = - 13 + 23

= 10

Step-by-step explanation:

In any order of operation (i.e. addition, subtraction, multiplication, devision) the following rules apply for two values for instance <em>a </em>and <em>b </em>where <em>a > b </em>:

→ <em>If +a and +b then the final sign will be + (positive)</em>

→ <em>If +a and -b then the final sign will be + (positive) since a>b</em>

→ <em>If -a and +b then the final sign will be - (negative) since a>b</em>

→ <em>If -a and -b then the final sign will be - (negative)</em>

In the given question we have two cases.

Case 1:

- 13 - 23 = - 13 + (-23)     <em>→ since it is given that we add a negative value of -23, therefore it keeps its sign (so this would be a negative addition i.e. adding two negative values)</em>

Thus we have:

- 13 - 23 = - 13 + (-23)

= -36

Case 2:

- 13 - (- 23) = - 13 + 23     <em>→ since we stated earlier that - and - gives positive sign (i.e. we subtract two negative values)</em>

Thus we have:

- 13 - (- 23) = - 13 + 23

= 10

<em>So we can see that: </em>

<em>Adding two Negative values gives a Negative value (Case 1)</em>

Subtracting two Negative values gives a Positive value (Case 2)

In October flowers cost $1.50 each. The October price was a 20% increase of the September price. What was the price of of the fl
Anvisha [2.4K]

Hey there!!

Let's write $1.5 as 15 / 10

15/10 = 3/2

$3/2

October price = $3/2

Let's take September price as ' x '

If we take a look at the question, we know

October price = 20% of September + September price

20% = 20/100 = 1/5

Of = multiplication

Plug in the values

3/2 = x/5 + x

LCM = 5

3/2 = 6x / 5

Multiplying by 5 on both sides

15/2 = 6x

Dividing by 6 on both sides

15/2 / ( 6 ) = x

15/2 × 1/6 = x

15/12 = x

15/12 = $1.25

The price in September = $1.25

Hope my answer helps!
