Answer:
Step-by-step explanation:
Just add 10 to both side and we'll have

20 < x < or equal to 35
Answer:
4,200 liters
Step-by-step explanation:
The flow rate is given by:

Integrating the flow rate expression from t=0 to t=30 minutes, yields the total volume that flows out of the tank during that period:

4,200 liters of water flow from the tank during the first 30 minutes.
Answer:
y= 19.5 x=33
Step-by-step explanation:
-x + 27= -6
(subtract 27 on both sides)
-x= -33
(divide by negative 1 on both sides)
x= 33
(substitute x into the first equation)
y= 1/2x + 3
y= 1/2(33) +3
y= 16.5 +3
y= 19.5
hope this helps :))
Since 2+8 =10 you would just have 3 left to add so it would be 10+3=13
