K would be =25. I’m sure the problem is asking for the coordinate points in the graph and at 1 on the x axis, the line lands on 25 on the y axis. This landing, causes k to be 25.
In total the cyclist was gone 5 hrs 5 mins, so when added to 10:25, you get him getting back at 3:30
Answer:
Step-by-step explanation:
Given
f(x) =
To evaluate f(a + 2) substitute x = a + 2 into f(x), that is
f(a + 2) = =
In this problem, there are 2 similar triangles: triangle FMN and triangle FGH.
Their ratio to each other is 1:2 which we know by the midpoints.
If they have a ratio of 1:2, line segment GH is the 2 times of line segment MN.
To find x:
Answer:
200 seats
Step-by-step explanation:
Let s = numbers of seats
1/5s = children
3/4 s = adults
10 = empty
The total number of seats = children + adults + empty
s = 1/5s + 3/4s + 10
Subtract 1/5s and 3/4s from each side
s -1/5s -3/4s= 1/5s-1/5s + 3/4s-3/4s + 10
s - 1/5s - 3/4s = 10
Get a common denominator
20s/20 - 4s/20 -15s/20 = 10
Combine like terms
1s/20 = 10
Multiply each side by 20
s/20 *20 = 20*10
s = 200
