Step-by-step explanation:
If you can get 3 shirts for $24 then that means that each shirt was $8. With that being said, 8 multiplied by 7 equals 56 so you would pay $56 for 7 shirts.
4 * 15 = 60
x * y = 60
x + y = 17
What two numbers multiply to get 60 and add to get 17
Answer: 80 minutes
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each tank:
An empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute.
So, the amount of water of the tank is equal to the filling rate, 6 liters per minute (6m)
- Tank 1 =0 (empty )+ 6m =6m
The second 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute.
So, the amount of water in the tank is equal to the amount of water already in the tank (1200 g), minus the draining rate (9m)
Since both tanks will have the same amount of water:
6m = 1200-9m
Solving for m (minutes):
6m+9m= 1200
15m = 1200
m= 1200/15
m= 80 minutes
Feel free to ask for more if needed or if you did not understand something.
Answer:
= 0.75
Step-by-step explanation:
-3x-9+15x = 0
12x = 9
x = 3
4
= 0.75
|-3| is the absolute value of -3 which is 3 and then the -3 is just as is.. if you were looking for how much is between the two numbers, you you simply count, like for these two it would be 6
