Answer:
Step-by-step explanation:
Complementary is adding up to 90 degrees. depends what the other angle is/one of the pair. Subtract that by 90 and you find the other angle.
First, write highlight the even numbers, then the multiples of 3
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
No, count how many have been highlighted at least once
16 out of 25 were highlighted
16/25
Or, there are 12 even numbers between 1 and 25. There are also 8 multiples of three, however half will be even
8/2 = 4
4 + 12 = 16
16/25
Answer:
See below.
Step-by-step explanation:
(5,4) and (-3,2)
2-4=-2
-3-5=-8
-2/8 or -1/4 is the slope.
3 is the y-intercept.
y=-1/4x+3

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
On the same plane. Not in a straight line but on the same plane
