Answer:
Step-by-step explanation:
First, we will eliminate the x, so we multiply the first one by 2.
4x+6y=4
4x-2y=4
So, we have y=0, and we put that in the equations, so x is 1

Answer:
0.48
Step-by-step explanation:
1x3/56 then multiply it by 9
1x3 is 3
3 x 9 = 27
27/56 this fraction cant be reduced so if you count it or put it in a calculator you'll get 0.482143
Answer:
first do:
60mph * 4 hours= 240mi
Let D = the distance the passenger train has to
travel to catch the freight train
Start a stopwatch when the passenger train leaves
Let t = the time on the stopwatch when they meet
Equation for freight train:
d-240=60t
Equation for passenger train:
d=100t
all together:
100t-240=60t
we can do 100t-60t because they both have (t)= 40t
40t=240 *now divide 240 by 40= 6
THEN do:
D= 100mph x 6= 600mi
They will meet 600 mi from the station
to check:
d-240=60t x 6
600-240= 360
60 x 6= 360
360=360
