Answer: b. C = 5 × ($0.75 × 4) 
Step-by-step explanation:
Note that 4 quarts = 1 gallon
Therefore, if a cleaning product sells for $0.75 a quart, the equation can be used to solve for the total cost, C , of five gallons of the product will be:
= 5 × ($0.75 × 4) 
= 5 × $3
= $15
 
        
             
        
        
        
The answer is (3p-5pt)/12
remove parenthesis but the terms are connected.
        
             
        
        
        
Answer:  
You can write this as (-infinity, 7) if you aren't able to use the infinity symbol.
====================================================
Explanation:
Think of x < 7 as writing 
So x is between negative infinity and 7, excluding both endpoints.
To write  in interval notation, we write
 in interval notation, we write  
 
The curved parenthesis tell us to exclude the endpoint.
 
        
             
        
        
        
Answer:
178.98 ft2
Step-by-step explanation:
we know that
The area of the circular path alone is equal to subtract the area of the circular garden from the area of the complete circle (circular garden plus circular path)
so

where
 ---> radius of circular garden
 ---> radius of circular garden
 ----> radius of the circular garden plus radius circular path
 ----> radius of the circular garden plus radius circular path
substitute
