The total volume of water in the tank after 3 mins 24.75 gallons.
<h3>New volume of water in the tank</h3>
The new volume of water that entered into the tank is calculated as follows;
V₁ = 0.1 L/sec x (3 x 60 s)
V₁ = 18 L
<h3>Volume of water in liters to gallon</h3>
1 liter = 0.264 gallons
18 Liter = ?
= 18 x 0.264
= 4.75 gallons
<h3>Total volume of water in the tank after 3 mins</h3>
V = 20 gallons + 4.75 gallons
V = 24.75 gallons

Answer:
- 5x+3
- x -7
- -x +7
Step-by-step explanation:
Combine like terms. The associative and commutative properties of addition apply, as does the distributive property.
__
1. (2x+5)+(3x-2) = (2x +3x) +(5 -2) = 5x +3
__
2. (3x-2)-(2x+5) = 3x -2 -2x -5 = (3x -2x) +(-2 -5) = x -7
__
3. (2x+5)-(3x-2) = 2x +5 -3x +2 = (2x -3x) +(5 +2) = -x +7

<em>Additional comment</em>
Note that swapping the order of operands in a subtraction problem (problems 2 and 3) will cause the sign of the result to reverse.
You want to know the two numbers that squared are on either side of 68.
8^2 and 9^2=64 and 81
So the two consecutive numbers are 8 and 9
