According to the equation located here: https://www.1728.org/glwarmng.htm burning one gallon of gasoline produces 19.3 pounds of carbon dioxide.
So, if a car gets 37 miles per gallon and if it travels 400 miles, it will use 10.81 gallons of gasoline and will produce 19.3 * 10.81 = 208.63 pounds of carbon dioxide.
A) 7.5/3=2.5
b) So about 3 pieces can be cut.
Infinitely Many Solutions because is you simplify either one, you get the same equation as the other.
The answer on top of me is correct
For example, evaluate 17*5*20:
Method 1: (17*5)*20 = 85*20 = 1,700.
Method 2: 17*(5*20) = 17*100 = 1,700.
Notice that by first multiplying 5*20 to get 100, the calculation
is easy to do in your head.
You can also use the commutative property to rearrange a question:
5*21*4 = 5*4*21 = 20*21 = 420
