Hello,
8d+3d-3d-8=3d;
8d-8=3d;
8d-3d = 8;
5d = 8;
d = 8/5

bye :-)

Let's start with deleting +3d and -3d (because they have opposite signs)

8d-8 = 3d

Move unknown term (3d) to the left of equal with changed sign and known term (-8) to the right of equal with chenged sign.

8d-3d = 8

5d = 8

Divide both for 5

5d/5 = 8/5

d = 8/5

The following table shows the length and width of two rectangles:
zhannawk [14.2K]

Answer:

10x - 8 or 2( 5x - 4)

Step-by-step explanation:

Perimeter of a rectangle = 2( Length + Width)

<u>Rectangle A </u>

Length = x + 8,

Width  = x - 1

Perimeter_A = 2((x + 8) + ( x - 1))\\\\

                 = 2(x + 8 + x - 1) \\\\= 2(2x + 7)\\\\=4x + 14

<u>Rectangle B</u>

Length = 4x + 5

Width = 3x - 2

Perimeter _B= 2((4x + 5) + (3x-2))\\\\

                 =2(4x + 5 + 3x - 2)\\\\=2(7x + 3)\\\\=14x + 6

Perimeter_B - Perimeter_A = (14x +6)-(4x + 14) \\\\

                                       =14x + 6 - 4x - 14\\\\=10x -8\\\\or \\\\=2(5x - 4)

Suppose you want to use elimination to solve this system.
Y_Kistochka [10]

If you want to eliminate x than multiply equation 1 by 4 and equation 2 by 3 and subtract them or,

If you want to eliminate y than mutiply equation 1 by 8 and equation 2 by 11 and subtract them.

In what quadrant would the ordered pair (-5, 4) be located?<br><br> I<br> II<br> III<br> IV
statuscvo [17]
Ok, so
 Quadrants are found on coordinate planes. So the first number tells you to go on the X axis. It goes this way ---------
you look on the left side side of the origin (zero) and go to -5
since the second umber will be found on the Y axis, and is positive, go up to 4.
That is how you find your point.  The qudrants are counted like this.
2 1 
3 4
The answer is Quadrant 2
Hope it helped☺

Da sofa is on sale for $98.60, which is 29% of the regular price. What is the regular price ?
yaroslaw [1]
Let the regular price be X
x\98.60 x 100=29%
100x\98.60=29(multiply both sides by 98.60 to remove the denominator
100x=2859.4(divide both sides by 100
x=28.594
regular price=$28.594
