Answer:
120km
Step-by-step explanation:
10km in 15 min
3hrs = 3 x 60 min = 180 min
180min divided by 15min = 12
12 x 10km = 120 km
Answer:
x - 2
Step-by-step explanation:
2x - 1 + 4x - 11
First, you want to combine like terms.
We can see that the one and eleven can go together, so add them together.
2x + 4x - 12
The reason that we made one, and eleven, negative twelve, is because they are both being subtracted from the numbers before that.
6x - 12
We added the 2x, and the 4x together to make 6x.
Another way to write this would be x - 2, because you can simplify it by dividing it by 6.
Answer:
the solution of linear equation 4b + 6 = 2 - 6 + 4 is b = -2
Step-by-step explanation:
We need to solve the linear equation
4b + 6 = 2 - 6 +4
Adding constants
4b + 6 = 0
Adding -6 on both sides
4b + 6 -6 = 0 -6
4b = -6
Dividing with 4 on both sides
4b/4 = -6/4
b = -2
So, the solution of linear equation 4b + 6 = 2 - 6 + 4 is b = -2
Answer:
25 = x
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
5x+15 = 6x -10
Subtract 5x from each side
5x-5x+15 = 6x-5x -10
15 = x - 10
Add 10 to each side
15+10 = x-10+10
25 = x
