2x-10+2x
answer is 10 because the the 2xs cancel each other out
Answer:
m∠BXC = 70°.
We start out with m∠XBC. It is 55°, because it is a corresponding angle with ∠AXY.
Since ∠XBC and ∠XCB are the base angles of an isosceles triangle, they are congruent. This means that m∠XCB = 55°.
To find the measure of ∠BXC, we find the sum of the two base angles in the isosceles triangle and subtract it from 180:
180-(55+55) = 180-110 = 70°
Step-by-step explanation:
Hello!
You solve inequalities just like equations by using inverse operations.
8x/8<120/8
x<15
16x/16>-100/16
x>-6.25
-5x/-5>80/-5
x>-16
x+20-20≤75-20
x≤55
x-15+15≥225+15
x≥240
x+130-130≤530-130
x≤400
I hope this helps!
Speed = distance / time
his travel speed TO the meeting.....
s = 480 / 8 = 60 miles per hr
his travel speed FROM the meeting...
s = 480 / 7.5 = 64 miles per hr
