Answer:
Dilations.
Step-by-step explanation:
A dilation does not preserve congruency since the post-image will be of a different size than the pre-image.
The answer is 270 because there is a 90° angle and 146n
Answer:
-3 thus the answer is B.
Step-by-step explanation:
Evaluate 7 - (5 x)/6 where x = 12:
7 - (5 x)/6 = 7 - 5/6×12
(-5)/6×12 = (-5×12)/6:
(-5×12)/6 + 7
12/6 = (6×2)/6 = 2:
7 - 52
-5×2 = -10:
-10 + 7
7 - 10 = -3:
Answer: -3
Answer:
x=4
Step-by-step explanation:
Amber coaches both sports for 7 hours each day
v = volleyball hours
s = soccerball hours
7 hours in total, in which soccerball is 1 hour more than volleyball:
v + s = 7
s = v + 1
plug in v + 1 for s
v + s = 7
v + (v + 1) = 7
simplify
v + v + 1 = 7
2v + 1 = 7
2v + 1 (-1) = 7 (-1)
2v = 6
2v/2 = 6/2
v = 6/2
v = 3
Plug in 3 for v for one of the equations.
s = v + 1
s = (3) + 1
s = 4
Amber coaches 3 hours for volleyball, and 4 hours for soccer, making a total of 7 hours
hope this helps
