So 48 • 4 would equal 192 so 4 • 2 mins equals 8 mins and then you have 8 more books to unpack so 48 divide by 8 equals 6. So the answer would bc (8 mins and 6 second)
        
             
        
        
        
The slope of the line is -1/7, so the perpendicular line has a slope of 7
        
             
        
        
        
Mya took out money from the bank. When she went to get a bank statement she saw she had a $-2.00 in her account but she needed the number so she took out $30. So you would do $30+(-2.00)=(-32.00)
        
             
        
        
        
Make the number 693,000 instead of 69,300. The answer would be 86,625.
