Find the error in the solution, and then solve it correctly. 7x + 12 + 3x = 8
7x + 12 = 5
7x = -7
x= -7/7

3х (or 3) was subtracted from the left side, but 3 (or 3x) was subtracted from the
right side. The Subtraction Property of Equality states that you can subtract the
same number from each side and the equation will remain true. But 3x and 3 are
not the same number (unless x is 1 ( or 0 or 2)
X =

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
