First, we can convert feet to inches 1 foot=12 inches 7 feet=84 inches Next, we find out inches per hour 84 inches/27 1/2 hours ----------- -------------- 27 1/2 27 1/2 =3.054 inches/hour
        
             
        
        
        
Answer:
a= 2 b=-1
Step-by-step explanation:
a-3b=5
or, a= 5+3b_(i)
substituting value of a in 2a+b=3,
2×(5+3b)+b=3
or, 10+6b+b=3
or, 7b=3-10
or, 7b=-7
b= -1
substituting value of b in(i),
a=5+3b
 =5+3×(-1)
 =5-3
 =2
