Answer:
60 mph
Step-by-step explanation:
Their average speed while driving is ...
speed = distance / time
= (270 mi)/((3 + 1.5) h) = 60 mi/h
The Johnson family averaged 60 mph <em>while driving</em>.
__
Their average speed for the trip is unknown, because we don't know how long the lunch stop was.

= 5a-a-y-3y-4-5 <---- Group like terms
= 4a-y-3y-4-5 <---- Add similar elements
= 4a-4y-4-5 <---- Add similar elements (cont.)
= 4a-4y-9

Answer:
A, C, D
Step-by-step explanation:
All three triangles can be proved congruent, so corresponding angles are congruent.
∆JKL ≅ ∆MNO ≅ ∆PQR
__
So, the statements that are true are ...
A) rigid motion can map ∆JKL to ∆MNO
C) ∆JKL can be proved congruent to ∆PQR
D) ∠N can be proved congruent to ∠Q
_____
<em>About the other choices</em>
B. When triangles are congruent, there is some rigid motion that maps one to the other. It is false to say there is none such.
E. ∠L has a measure of 65° (not 55°), as do the corresponding angles in the other triangles.
I believe the first one 12+ 6 + 15 = 12 + 15 + 6 is your answer, since you are just moving things around
hope this helps
Answer: 54.29%
Step-by-step explanation:
Given: The probability that they will win both games is 38%.
i.e. P( both games will win) =0.38
The probability that they will win just the first game is 70%.
P(first game will win) = 0.70
To find : P(second game will win| first game will win)
Using formula: 
So, P(second game will win| first game will win) = 
Hence, the required probability = 54.29%
