Answer:

  46

Step-by-step explanation:

The length of base CD is twice the length of midsegment FG, so you can write the equation ...

  CD = 2×FG

  -3x +52 = 2(13 +5x)

  52 = 26 +13x . . . . . . . . add 3x, simplify

  26 = 13x . . . . . . . . . subtract 26

  2 = x . . . . . . . . . . divide by 13

Then the measure of CD is ...

  CD = -3x +52 = -3(2) +52 = -6 +52

  CD = 46

Write 8/4 as a mixed number. how did you come to your answer
Sergeeva-Olga [200]
To write in the mixed fraction you have to simply divide 8 and 4. 
To right in the mixed number we need to know numerator, denominator and divisor. 
So in your problem our divisor is 4, 
so now lets divide it 
\frac{8}{4}
=  \frac{2}{1}

So, now we have to write it as mixed number..
mixed number  will be 
2  \frac{0}{8}

Hope this helped you.. :)
