Answer:
x = 1/12
Step-by-step explanation:
2/3x + 1/4 = (8x+3) /12   (create equivalent fractions with a denominator of 12)
23/3x - 1/3 = (23x - 1) /3            *(46/6x = 23/3x)
 <u>8x + 3</u>  =  <u>23x - 1</u> 
     12            3
now cross-multiply:
3(8x + 3) = 12(23x - 1)
24x + 9 = 273x - 12
9 = 252x - 12
21 = 252x
x = 21/252 which reduces to 1/12
 
        
             
        
        
        
Answer:
11 units
Step-by-step explanation:
Given : She has mapped the arrangement on a coordinate pane. A,B and C represent the sofas, V1 and V2 are decorative vases and AQ the aquarium
To Find: The distance between V1 and the aquarium.
Solution: 
Referring the given image 
We can have the coordinates of V1 and AQ
Coordinates of V1 :
Coordinates of AQ :
Now To find distance use distance formula

![d=\sqrt{(5-[-6])^{2} + (5-5)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%285-%5B-6%5D%29%5E%7B2%7D%20%2B%20%285-5%29%5E%7B2%7D%7D)




Hence The distance between V1 and the aquarium is 11 units
