Can anyone me with this and give me steps because i can’t figure it out

The answer to your question is:   BD = 7.5

Step-by-step explanation:

Data

C is the midppoint of AD

B is the midpoint of AC

AC = 5

BD = ?

Process

We know that B is the mid point of AC, then AB = BC

                                  AB + BC = 5

                      but              2AB = 5

                                         AB = 5/2

                                        AB = 2.5  = BC

Then   AC = CD if   AC = 5 then CD = 5

Finally

                     BD = BC  + CD

                     BD = 2.5 + 5

                     BD = 7.5

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

x + 4/7
