Answer:
3.5 cm
Step-by-step explanation:
6x -1 = 4x + 6
2x = 7
x = 3.5
I would estimate 643 - 189 by rounding 643 to the tens place and 189 to the hundreds place.
643 => 640
189 => 200
Now you can subtract 200 from 640.
640 - 200 = 440
The answer would be “undefined”
Answer:
B.
Step-by-step explanation:
6 is left after crossing from end to end.
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
