Points a, b, c, and d lie on line segment ad. if ab = x, bc = x + 3, cd = twice the length of bc, and ad = 53, what is the value of x? what is the length of bc?

 x=11,   BC  = 14

Step-by-step explanation:

Points A, B, C, and D lie on line segment AD. If AB = x, BC = x + 3, CD = twice the length of BC, and AD = 53, what is the value of x? What is the length of BC?

AB=X             AB=11

BC=X + 3      BC= 11 + 3= 14

CD= 2(X + 3)  CD= 2(11 + 3)= 28

11+14+28=53

AD= 53

X + X + 3 + 2(X + 3) =53

2x+3+2x+6=53

4x+9 =53

   -9= -9

  4x =44

  4      4    

     x=11

length of BC is 11 + 3 = 14

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

squares, rhombus, rectangles
