There's two ways, you can either multiply 11 and 7 to get 77 and then divide by 2, OR, you can divide 11 by 2 and get 5.5 and multiply that by 7, hope this makes sense, if you don't understand just comment and I'll explain it more :)
        
             
        
        
        
Answer:
6 feet 
Step-by-step explanation:
Volume of a rectangular prism = L × W × H 
15 feet × 8 feet × H = 720 feet ³ 
120H = 720
H = 720 ÷ 120
H = 6 feet

The solution of the equation is x = 71 / 36.
<h3>How to solve an equation with one variable</h3>
Herein we have an equation with several rational constants and only one variable, x, which has to be cleared by using algebra procedures. The procedure is shown below:
2 · x + 1 / 3 + x - 1 / 4 = 13 / 2           Given
2 · x + x = 13 / 2 - 1 / 3 - 1 / 4            Compatibility with addition / Existence of additive inverse / Modulative property
3 · x = 71 / 12                                    Definitions of addition and subtraction / Distributive property
x = 71 / 36                                         Compatibility with multiplication / Existence of multiplicative inverse / Modulative property / Result
The solution of the equation is x = 71 / 36.
