To take a taxi, it costs $ 3.00 $3.00dollar sign, 3, point, 00 plus an additional $ 2.00 $2.00dollar sign, 2, point, 00 per mile traveled. you spent exactly $ 20 $20dollar sign, 20 on a taxi, which includes the $ 1 $1dollar sign, 1 tip you left. how many miles did you travel?

8 miles

Explanation:

Explanation:

We have a taxi ride where the total fare is $3 plus $2 for every mile travelled plus a $1 tip and the whole thing is $20.

Let's first write a formula that expresses the cost of the ride:

Total cost

=

Flat fee

+

Mileage

+

Tip

Now let's drop in what we know:

20=3+2(miles)+1

- we know the total cost of 20, the fee of 3, the tip of 1 and the cost per mile of 2. The only thing we don't know is the number of miles. So let's solve for that.

First we subtract 3 and 1 from both sides and get:

16=2(miles)

Then we divide both sides by 2:

8=miles

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
