Answer:
4.5
Step-by-step explanation:
0.5p-3.45=-1.2
add 3.45 to -1.2 which would leave the equation to look like
0.5p=2.25
then divide 0.5 to both sides cancelling 0.5 leaving the answer to be
p=4.5
 
        
             
        
        
        
Answer:
there is the thing you need to answer the question right
Step-by-step explanation:
 
        
             
        
        
        
1 hour=3600 seconds
1 mile=5280 feet
87 miles/hr (1 hr/3600 sec)(5280 ft/mile)=127.6 feet/sec
Distance= Rate*time
d=127.6(12)=1531.2 feet (after 12 seconds) 
        
             
        
        
        
775 miles. Divide 7.75 by .5 and then times the answer by 50.
