<span> r + s = -12 so r = -s - 12
</span><span>4r - 6s = 12
substitute </span>r = -s - 12 into 4r - 6s = 12
4r - 6s = 12
4(-s - 12) - 6s = 12
<span>-4s - 48 -6s = 12
-10s = 60
s = -6
r = -(-6) - 12
r = 6 - 12
r = -6
answer
</span><span>B -6,-6</span><span>

Answer:
-3, -4, -5
Step-by-step explanation:
x = 1st integer
x+1 = 2nd integer
x+2 = 3rd integer
x+x+1 = 3(x+2)
2x + 1 = 3x + 6
1 = x + 6
-5 = x
-4 = x+1
-3 = x+2

Answer:
14. C) 136°
15. C) 40°
Step-by-step explanation:
Inscribed angles are half the measure of the arc they intercept. For an inscribed quadrilateral, this means opposite angles are supplementary.
__
14) ∠H +∠W = 180°
34x +55x +2 = 180
89x = 178 . . . . . . . . . subtract 2
x = 2 . . . . . . . . . . . . . divide by 89
arc VX = 2(34x) = 68(2) = 136 . . . degrees
__
15) The sum of angles in the triangle is 180°.
? + 80° + (120°/2) = 180°
? = 40° . . . . . . . . . . subtract 140°
