⇒We have to estimate the difference

 =610 - 187

Actual Estimation=  423

⇒Estimation using Tens

 =610 - 190

 = 420

⇒Estimation using Hundreds

 =600 - 200

= 400

→Correct estimation is

Estimation using Tens=420

What does x represent for these 4 problems?
Tanya [424]
1.

-2x = 10

x = 10/(-2)

x = -5

2.

1/2 x = 5

x = 5 * 2

x = 10

3.

5x = -20

x = -20/5

x = -4

4.

9x = 36

x = 36/9

x = 4

Which equation represents a circle with a center at (2,-3) and a radius of 11
Verdich [7]

Answer:

x^2-4x+y^2+6y-108=0

Step-by-step explanation:

The- equation- of- circle- with -center- at- (h,k) -and -a -radius- of- r -is: \\(x-h)^2 +(y-k)^2 = r^2\\h = 2 , \\  k = -3\\r = 11\\(x-2)^2+(y-(-3))^2 = 11^2\\(x-2)^2+(y+3)^2 = 121\\x^2-4x+4 +y^2+6y+9 = 121\\x^2 -4x+y^2+6y+4+9=121\\x^2 -4x+y^2+6y+13=121\\x^2 -4x+y^2+6y=121-13\\x^2 -4x+y^2+6y= 108\\x^2 -4x+y^2+6y-108 = 0

The dimensions of a square are altered so that 8 inches is added to one side while 3 inches is subtracted from the other. The ar
Alex_Xolod [135]

Answer

Find out the original side length of the square .

To prove

Let us assume that the original length of the square be x.

Formula

Area\ of\ rectangle = Length\times Breadth

As given

The dimensions of a square are altered so that 8 inches is added to one side while 3 inches is subtracted from the other.

Length becomes  = x + 8

Breadth becomes = x -3

The area of the resulting rectangle is 126 in²

Put in the formula

(x + 8) × (x - 3) = 126

x² -3x + 8x -24 = 126

x ²+ 5x = 126 +24

x² + 5x - 150 = 0

x² + 15x - 10x - 150 = 0

x (x + 15) -10 (x +15) =0

(x + 15)(x -10) =0

Thus

x = -15 , 10

As x = -15 (Neglected this value because the side of the square cannot be negative.)

Therefore x = 10 inches be the original side of the square.
