Answer:x = 3
y = 9
Explanation:1- getting the value of x:We are given that:
side AB is congruent to side DF. This means that:
AB = DF
3(2x+10) = 12x + 12
6x + 30 = 12x + 12
12x - 6x = 30 - 12
6x = 18
x = 18/6
x = 3
2- getting the value of y:We are given that:
side BC is congruent to side FG. This means that:
BC = FG
2y + 12 = 2(2y-3)
2y + 12 = 4y - 6
4y - 2y = 12 + 6
2y = 18
y = 18/2
y = 9
Hope this helps :)
 
        
        
        
<span>The list of
scores will be: 30 60 63 65 65 67. To get the median, you have to
arrange the scores from lowest to highest. The middle number is the median. In
this, case there are two numbers in the middle so you have to add the two and
then divide by two.</span>
<span>Therefore, 63 +
65 = 128 / 2 = 64.</span>
        
             
        
        
        
The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal, it is obtained by Pythagoras theorem. 
Step-by-step explanation:
The given are,
            From ΔABC,
                     AB= 6
                     BC= 10
                     AC = x
            From ΔDEC,
                     CD= 28
                     DE= 21
                     CE = y
Step:1
         Pythagoras theorem from  ΔABC,
                      ...............(1)
...............(1)
        Substitute the values,
                     =
 =  +
 + 
                   100 = 36 + 
                     = 100 - 36
 = 100 - 36
                            = 64
                     AC = 
                     AC = 8
                    AC = x = 8
Step:2
         Pythagoras theorem for ΔDEC,
                 ................(2)
................(2)
        From the values,
                =
 =  +
 + 
               = 784 + 441
 = 784 + 441
                      = 1225
               CE = 
               CE = 35
               CE = y = 35
Result:
          The values are x=8 and y=35, if the given ΔABC and ΔDEC are equal.
