Answer:
C
Step-by-step explanation:
First, Karen only has $20, so her spending cannot go over this amount. That would would that she can spend exactly $20 or less than $20. We need a equal to/less than sign before $20, so answer choices A and D can easily be eliminated.
Next, the admission costs $6. This is a cost that Karen will only pay one time, so it's represented by + 6. This eliminates B, but I will still explain why C is completely correct.
Each ride costs $2, meaning that we can represent this amount with 2x, which is just $2 times the amount of rides she will go on. When fully written out, the inequality is 2x + 6 (less than or equal to sign) 20, making C the correct answer.
Answer:
7.5

4x+5=2x+20
Answer:
Velocity of jet in still air is 800mph hour and velocity of wind is 180mph
Step-by-step explanation:
Let the velocity of jet in still air be x miles per hour and velocity of wind be y miles per hour.
#Jet's velocity against jet-stream is:

#Jet's velocity with jet-stream:

#The velocity against jet-stream is x-y and with jet-stream is x+y:

Hence,velocity of jet in still air is 800 mph hour and velocity of wind is 180 mph.
Answer:
Angle A = Angle X
Line Segment CA = Line Segment ZX
Angle Y = Angle B
Line Segment YX = Line Segment BA
Step-by-step explanation:
Both triangles are stated to be equal so we can draw two triangles and label them. One triangle has Point A, Point B, and Point C. The second triangle has Point X, Point Y, and Point Z. Make sure that Point X on the second triangle is in the same spot as Point A on the first triangle (same for points B, C, Y, and Z).
