Answer:
False
Step-by-step explanation:
5-2(3-x) =
3(3-x) = (not sure about this step)
9-x, this answer does not equal 4x + 10

Answer:
72km/h
Step-by-step explanation:
Convert units to kilometers and hours.
275 seconds ÷ 60² ≈ 0.0764 hours
5500 meters ÷ 1000 = 5.5 km
Convert to kilometers/hour.
5.5km ÷ 0.0764hrs = 72km/h
What do you really mean..?
Answer:
x = 36
Step-by-step explanation:
The angles 3x - y and 2x + y form a straight angle and are supplementary, so
3x - y + 2x + y = 180
5x = 180 ( divide both sides by 5 )
x = 36
-----------------------------------------------
5y and 3x - y are vertical angles and congruent, hence
5y = 3x - y ( add y to both sides )
6y = 3x ← substitute x = 36
6y = 3 × 36 = 108 ( divide both sides by 6 )
y = 18
