Answer:
The first step to solve the equation below is to first distribute the 2 to (x+7)
Step-by-step explanation:
2 (x+7) = -4x + 14
2x + 14 = -4x + 14
 
        
                    
             
        
        
        
Answer:35
Step-by-step explanation:
We add or subtract from left to right to find the value of the expression:
3
Because the result is negative, she is below the cave entrance (by 35 feet).
 
        
                    
             
        
        
        
When we substitute a specific valuefor each variable, and then perform the operations, it's called evaluating theexpression. Let's evaluate theexpression 3y + 2y when 5 = y. Click on the steps to see how it's done. Perform the operations, to find the value of the expression.
        
                    
             
        
        
        
She can buy 3 tubes be cause 8.50 time 2 is less then 20$ but 8.50 times three is more than 20$ its 25.5
