Answer:
x= -19
Step-by-step explanation:
2x-4x-9=29
-2x=29+9
x=38/-2
= -19
Answer:
y=5
Step-by-step explanation:
13.01d - 2.65 because 3.26d and 9.75d combine (they’re like terms) and subtracting 2.65 stays the same because there are no like terms for that one
Answer:
D
Step-by-step explanation:
The formula for the circumference of a circle is 2
r. So if we know that C=60
then we can trace our steps back. We are given that pi remains constant so we are left with the 2r from the formula and a 60. 60/2 =30.
The radius is 30cm

so... that's how much an internal angle is
now, subtract that from 180 and you get the angle outside, in the picture
subtract that outside angle twice from 180, and you get angle "2"
because angle 2 is in the same triangle as those two outside angles, and all internal angles in a triangle is 180, thus 180 - (those two angles) is angle "2"
