Step-by-step explanation: To solve for x in this inequality,
your goal is the same as it would be if you were solving an
equation, to get x by itself on one side.
Since 5 is being subtracted from x, add 5 to both sides of the inequality.
On the left, the -5and +5 cancel out and on the right, -2 + 5 is 3.
So we have x ≥ 3.
When graphing, start with a closed dot at +3 because x is
not just greater than +3, it's equal to it as well.
Then draw an arrow to the right, like I have done below.

Answer:
Train A's unit rate is 67 km per hour.
Train B's unit rate is 75 km per hour.
Train B is faster than Train A
Step-by-step explanation:
Train A
Distance traveled by Train A is represented by :
where represents distance traveled in kilometers and
is the time in hours.
To find the unit rate of Train A, we will plugin and get the distance traveled by Train A in 1 hour which will be the unit rate of Train A in km/hr.
So, distance traveled by Train A in 1 hour = 67 km
∴ Train A's unit rate is 67 km per hour.
Train B
For Train B, we are given the table for the time in hours and distance traveled in that duration.
Taking time =2 hours the distance traveled by Train B= 75 km
To find distance traveled in 1 hour we apply unitary method.
So
So, distance traveled by Train B in 1 hour = 75 km
∴ Train B's unit rate is 75 km per hour.
Difference in units rates =
On comparing their unit rate i.e. the speed of the trains we find out that Train B is faster than Train A by 8 km/hr
Answer:
Step-by-step explanation:
We have given the numbers = 2,0,1,9
We can use addition and subtraction operation to the given numbers such that the answer will be equals to 6.
We can add 2 ,0 and 1 and then subtract from 9 , we will get 6.
So the required expression can be
hence, the required expression can be
