antiseptic1488 [7]3 years ago
4 0

Answer:

x=10

Step-by-step explanation:

BD/CD=AB/AC

x+4/2x+1=8/12

12(x+4)=8(2x+1)

12x+48=16x+8

12x+48-8=16x+8-8

40=4x

40/4=4x/4

10=x


Hope this helps! ;)

Equivalent fractions are fractions that can be simplified down to the same thing.

For example, 9/18 can be simplified down to 1/2

So, 1/2, 3/6, 4/8, 5/10, 6/12, etc are all equivalent fractions because they too can be simplified down to 1/2
