Step-by-step explanation:
119°+29°+n°=180°. (Sum of all the angles of triangle)
So,
158°+n= 180°
n= 180°-158°
n= 22°
<span>x in (-oo:+oo)
(x+20)/2 = 3*x // - 3*x
(x+20)/2-(3*x) = 0
(x+20)/2-3*x = 0
(x+20)/2+(-3*2*x)/2 = 0
x-3*2*x+20 = 0
20-5*x = 0
(20-5*x)/2 = 0
(20-5*x)/2 = 0 // * 2
20-5*x = 0
20-5*x = 0 // - 20
-5*x = -20 // : -5
x = -20/(-5)
x = 4 so x= 4</span>
Answer:
2, 5, 8, 11, 14
3/2
explanation:
linear functions go up by the same x and same y (f(x))
so while x is going up by 2, y is going up by 3
y/x
the rate of change is 3/2
Answer:
9pm Monday
Step-by-step explanation:
It would take 12 hours, that would be when all of the medicines would be taken at the same time, because 3/4/6 are factors of 12
The speed of the train in miles per hour which is the ratio of the total distance covered and the total time taken to cover the distance is 9.79 mph
- Total distance covered = 7 and 5/6 miles = 7.83333 miles
- Total time taken = 4/5 of an hour = 0.8 hour
Recall :
Speed in miles per hour = Distance covered / time taken
- The speed of the train = 7.833333 ÷ 0.8 = 9.7916
- The speed of the train in miles per hour = 9.79 mph
Therefore, the speed of the train in miles per hour as calculated from the distance covered by the train over a certain period of time is 9.79 mph
