Answer:
(-1/4, 19/4)
Step-by-step explanation:
5x+6=9x+7
-4x=1
x= -1/4
y=5(-1/4) +6
y=19/4
Answer:
rounding to the nearest tenth

Answer:
The time the two planes will meet is 1.43 hours
Step-by-step explanation:
Given;
speed of the first plane in positive direction, = 40 mph
speed of the second plane in negative direction(opposite direction) = -100 mph
distance between the two planes = 200 miles
Let the time the two planes will meet = t
the position of the first plane at this time "t" = 40t
the position of the second plane at this time "t" = -100t
(40t)>--------------------------------<(-100t), this space between them is 200 miles.
Thus, the difference in the distance they traveled before meeting should be equal to 200 miles.
40t - (-100t) = 200
40t + 100t = 200
140t = 200
t = 200 / 140
t = 1.43 hours
Therefore, the time the two planes will meet is 1.43 hours
Amount decrease = 380 - 225 = 155
percent = 115/380 * 100 = 40.8 %
There is no picture given but I’m assuming you need to simplify it. The answer is 9x + 12
