Answer:
28 short-sleeved shirts were sold and 23 long-sleeved shirts were sold.
Step-by-step explanation:
We can solve this question by a system of equations.
I am going to say that:
x is the number of short-sleeved shirts sold.
y is the number of long-sleeved shirts sold.
A department store sold 51 shirts one day.
This means that 
All short-sleeved shirts cost $14.00 each and all long-sleeved shirts cost $23.00 each. Total receipts for the day were $921.00.
This means that

How many of each kind of shirt were sold?
We have to solve the system of equations.

From 11 am to 2:15 pm it is 3 hrs and 15 min
Answer:
x>-2
Step-by-step explanation:
Simplify both sides of the inequality.
4x+3>−5
Subtract 3 from both sides.
4x+3−3>−5−3
4x>−8
Divide both sides by 4.
4x/4>-8/4
What you do is solve all of the equations using the coordinates given for l and m
7/9 is greater than .7 because when you turn 7/9 into a decimal you get 0.7 repeating decimal, which you can round to get 0.8 which is greater than 0.7. So furthermore, you can conclude that 7/9 is bigger than 0.7 which is your answer :)
