I believe you divide 1656 and 8 which got me 207
Answer:
-5/3, or in decimal form, -1.666.
Step-by-step explanation:
a. -146 (3k+5) --- distribute the -146 to "3k" and "+5."
b. -438k - 730 = 0 --- get the variable k to one side of the equation.
c. -438k=730 --- divide by -438 on both sides.
d. the answer you get is 730/-438, which, in simpler terms, is -5/3, or -1.666.

Answer:
56°
Step-by-step explanation:
The two marked angles are supplementary, so total 180°.
(2x +8) +(x -2) = 180
3x +6 = 180 . . . . . . . . . . collect terms
x + 2 = 60 . . . . . . . . . . . divide by 3
x = 58 . . . . . . . . . . . . . . subtract 2
∠DCB = x-2 = 58 -2
∠DCB = 56
Y=Mx+b
Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)
Slope is -1/2
Yint = -8
So the equation is y=(-1/2)x - 8
