Section 2: Reasoning in Algebra –(one point per line, 6 total)
Fill in the reason that justifies each step.
(not to scale!!!)
Given: AD is 78 units long.
AC = 4x CD = 2x+12, AD = 78
a. _______________________________________
AC + CD = AD
b. _______________________________________
4x + 2x + 12 = 78
c. _______________________________________
6x +12 = 78
d. _______________________________________
6x = 66
e. _______________________________________
x = 11
f. _______________________________________
