You would divide 198 by 9.
198÷9=22
Each person would clean 22 rooms.
Answer:
-24n+64
Step-by-step explanation:
just distribute
Step-by-step explanation:
Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.
52 = ½ (x − 38)
x = 142
Arc angles add up to 360.
360 = 80 + 38 + z + x
z = 100
Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.
y = x/2
y = 71
Answer:
Step-by-step explanation:
1) 97 + x = 64 + 27 {Exterior angle property}
97 + x = 91
x = 91 - 97
x = -6
2) 4x + 17 + 80 + x + 23 = 180 {Angle sum property of triangle}
4x + x + 17 +80 + 23 = 180
5x + 140 = 180
5x = 180 - 140
5x = 40
x = 40/5
x = 8
The answer is (x-4)(x-12)
