An American traveler who is heading to Europe is exchanging some U. S. dollars for European euros. At the time of his travel, 1 dollar can be exchanged for 0.91 euros. Find the amount of money in euros that the American traveler would get if he exchanged 100 dollars.
euros

What if he exchanged 500 dollars?
euros

Write an equation that gives the amount of money in euros, e, as a function of the dollar amount being exchanged, d.
e = d

Upon returning to America, the traveler has 42 euros to exchange back into U. S. dollars. How many dollars would he get if the exchange rate is still the same?

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
