Answer:
3.8 miles
Step-by-step explanation:
Lillian wants her mileage total to be ...
12 +3x = 23.4 . . . . an equation that can be used to find x
4 + x = 7.8 . . . divide by 3
x = 3.8 . . . . . . subtract 4
Lillian would have to ride an average of 3.8 miles each day to reach her goal.
You could either convert 0.56 to a percent, thus making it 0.56%, or convert 65% to a decimal, thus making it 0.65.
65% would be greater.
