What is the value of x in this equation? 5x + 12 = -18

Answer:

<em>x</em><em> </em>= -6

Explanation:

First we collect like terms

<em>5x</em><em> </em><em>=</em><em> </em><em>-18</em><em> </em><em>-</em><em> </em><em>1</em><em>2</em>

<em>5x</em><em> </em><em>=</em><em> </em><em>-30</em><em> </em>

( because when both signs are the same we add them)

Then we decide both sides by five so that only x will remain

<em>5x</em><em> </em><em>/</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>-30</em><em> </em><em>/</em><em> </em><em>5</em>

<em>x</em><em> </em><em>=</em><em> </em><em>-6</em>

Thus, the value of <em>x</em><em> </em>is -6

Answer:

x = −6

Step-by-step explanation:

I like to start off by simplifying the equation! Then, I use inverse operations to narrow it down until I reach the answer!

5x + 12= −18

5x + 12 <u>− 12</u>= −18 <u>− 12 </u>

5x = −30

5x<u>/5</u> = -30<u>/5</u>

<u>x = -6</u>

valentina_108 [34]
7x+8(x+1/4) = 3(6x-9)-8
7x+8x+2      = 18x - 27 -24
15x + 2        =  18x - 51
       +51                        + 51
15x + 53      = 18x
-15x             = -15x
          53       = 3x

Answer:

No

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

We see that: 4.1 + 1.3 < 8.4

=> Can't  form a triangle from 4.1 cm, 8.1 cm and 1.3 cm

The perimeter of a rectangle is 36m. If its length is increased by 1m and the width is increased by 2m, its area will increase b
maw [93]

Answer:

  80 m^2

Step-by-step explanation:

The given information lets you write two equations involving length (x) and width (y).

  • 2(x +y) = 36 . . . . the perimeter is 36 m
  • (x+1)(y+2) -xy = 30 . . . . increasing the length and width increases area

The second of these equations simplifies to another linear equation, giving a system of linear equations easily solved.

  xy +y +2x + 2 -xy = 30

  2x +y = 28 . . . . . . . subtract 2

Dividing the first equation by 2 gives

  x +y = 18

and subtracting this from the above equation gives ...

  (2x +y) -(x +y) = 28 -18

  x = 10

Then

  y = 18 -10 = 8

The area of the original rectangle is xy = 10·8 = 80 m^2.
