Katyanochek1 [597]
The original number is 72 


(18+x)/6 = 1+14 
1/6x + 3 = 1 + 14 (Distribute)
1/6x + 3 = (1+14) (Combine Like Terms)
1/6x + 3 = 15 
        - 3 = -3          (Subtract 3 From Both Sides)
1/6x = 12 
(1/6x)*6 = 12 * 6  (Multiply Both Sides By 6)
x = 72

Find the distance between the two points~<br>A ( 7 , 4 ) and B ( 3 , 2 )<br><br><br>thankyou!​
vodka [1.7K]

Answer:

AB = \sqrt{20}

Step-by-step explanation:

calculate the distance using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = B (3, 2 ) and (x₂, y₂ ) = A (7, 4 )

AB = \sqrt{(7-3)^2+(4-2)^2}

     = \sqrt{4^2+2^2}

     = \sqrt{16+4}

     = \sqrt{20}

     ≈ 4.47 ( to 2 dec. places )
