Answer:

9x=15, and x= 1.6 infinite

Step-by-step explanation:

5:x=9:3 is basically 5/x=9/3 if there is 9x, it is equal to 5*3, or 15.

It is 9x because they did cross multiplication

So do it to the other side

and the answer is 9x=15

Answer:

BC = 22

Step-by-step explanation:

BD = 67

Bc = 3x - 2

CD = 4x + 13

BC + CD = BD (Given)

3x - 2 + 4x + 13 = 67

3x + 4x -2 + 13 = 67

7x + 11 = 67

7x = 67 - 11

7x = 56

x = 56 ÷ 7

x = 8

now instead of x put 8

Bc = 3x - 2

BC = 3(8) -2

BC = 24 -2

BC = 22
