Question

1. What is the value of x?
2. What is the value of y?
3. What is the value of z, to the nearest tenth?http://www.intervisualtechnology.us/data/1/9053/apply_12_4.png

Answer 1

1. X= 10*x = 6*9 = 10*x = 54 = 54 divide by by 10 (x = 5.4)
2. Y = ½(85+45) = y = ½(130) = (y = 65)
3. (6+6+9)6 = 11.23^2 ( z = 11.23)
is that the correct answer?
