Answer:
90ml
Step-by-step explanation:
all we need to do is find 60% of 150
60% of 150 is 90
Y= 2.75 add 3 to both sides and divide by 2 (2y - 3 = 2.5)
x= 4.5 subtract 8 from both sides and divide by 6 (6x + 8 = 35)
The average is (time)/(number of problems)=(45/60)/20=(3/4)/20=3/80 hours per problem. In minutes, the answer would be 3/80*60=9/4 minutes per problem.
Since the scale factor is smaller than one (the original), the resulting image is smaller than the original.
