a = 180°-60°-35° (Sum of angles in a triangle)
= 85°
b = 180°-85° (Sum of angles on a straight line)
= 95°
Answer: b is the answer

Answer:
Step-by-step explanation:
Let n represent the current age of the niece. Then 4n is Larry's current age. 4 years ago, the relationship was ...
6(n -4) = 4n -4
6n -24 = 4n -4
2n = 20
n = 10
Larry is 40; his niece is 10.
The answer is <span>B. (6, 0)
</span>
Let's check all solutions
<span>A. (0, 6)
a = 0
b = 6
</span><span>4a – 5b = 24
4*0 - 5*6 = 24
0 - 30 = 24
-30 = 24
INCORRECT
</span>B. (6,0)
a = 6
b = 0
4a – 5b = 24
4*6 - 5*0 = 24
24 - 0 = 24
24 = 24
CORRECT
C. (-5, - 2)
a = -5
b = -2
4a – 5b = 24
4*(-5) - 5*(-2) = 24
-20 + 10 = 24
-10 = 24
INCORRECT
D. (-2, -5)
a = -2
b = -5
4a – 5b = 24
4*(-2) - 5*(-5) = 24
-8 + 25 = 24
17 = 24
INCORRECT
