Answer:
Savannah
Step-by-step explanation:
Emery has solved it incorrectly;
x = 100
I think that the answer would be D) because there is no way to simplify the first equation. Hope this helps!

Step-by-step explanation:
(4)
arc XY is twice the inscribed angle YWX, thus
XY = 2 × 37° = 74°
The sum of the 3 arcs on the circle = 360°, thus
WY = 360° - (135 + 74)° = 360° - 209° = 151°
--------------------------------------------------------------------
(6)
arc QL = 2(3x + 23) = 6x + 46
QL + LK + KQ = 360, substitute values
6x + 46 + 9x - 6 + 140 = 360
15x + 180 = 360 ( subtract 180 from both sides )
15x = 180 ( divide both sides by 15 )
x = 12
Answer is c
a and d are crossed off because the action of going up and down is adding and subtracting. Absolute values of any number is a positive. So b and c are left. Then b is crossed out because the is subtracting each value from another which affects the result. Negatives change signs. Positives don't. So you want an equation that sums up all individual values without affect the signs. Answer is C.
