Hey there!
Let's combine like terms!
First, let's write them together, like so:
-2.8d+2.8d-2.8d+2.8d-1.33+3.4-1.33
And now we can see that -2.8d and 2.8d cancel out:
-2.8d+2.8d-1.33+3.4-1.33
And they cancel out again:
-1.3+3.4-1.33
Now all we have to do is add the numbers together:
0.77
Hope it helps!
Solution:
The first car can travel 75 miles on 5 gallons of gas.
So per mile gas consumed by car gallon
The second car can travel 240 miles on 20 gallons of gas.
So per mile gas consumed by car gallon
It mean Sam should rent the First car.
Sam is renting one of two cars to go on a 300-mile trip.
So total number of gallons of gas required
Total cost of 20 gallons of gas dollar
I hope this helps you
