180/3 = 60
Therefore the car traveled 60km per hour.
Add 2x to both sides,
3x+9=18
Subtract 9 from both sides. 3x=9
Divide both sides by 3.
x=3
Lin : 1.5 km in 5 minutes = 1.5 / 5 = 0.3 km per minute
Andre : 2 km in 8 minutes = 2 / 8 = 0.25 km per minute
so Lin is biking faster
Given that the associative property of multiplication says that you can group the numbers in any combination, we can reorganize the expression as: 7·(10·3)=210. So the answer would be the first option.
