Answer:Since the vehicles are travelling in the exact opposite direction, the sum of their rates is the rate at which they are separating. 48 + 64 = 112 miles per hour of separation.
728 miles ÷ 112 miles/hour = 6.5 hours
Step-by-step explanation:
Answer:
x = 6
y = -6
Step-by-step explanation:
By adding both equations :-
=》-4x -2y + 4x + 8y = -12 + (-24)
=》-4x + 4x + 8y - 2y = -12 - 24
=》6y = -36
=》y = -36 ÷ 6
=》y = -6
putting the value of y in equation 2
=》4x + 8y = -24
=》4x + (8 × -6) = -24
=》4x - 48= -24
=》4x = 48 - 24
=》x = 24 / 4
=》x = 6
Answer:
105 points.
Step-by-step explanation:
The scores of team A and B is 16 and 21.
if 16 = 80, The ratio of 16 to 21 is 5.
So, that means 16 x 5 is 80.
How many points did team B get?
score x gap between 16 to 21
= 21 x 5 = 105.
the team B got 105 points.
