Answer:
-45
Step-by-step explanation:
v=179-224
v=-45
v=-45
We are given eqaution:
, where e the amount of euros and d is the value as U.S. Dollars.
We need to find number of euros for 1 U.S. Dollar.
Plugging d=1 in the given equation
We get

On simplfying , we get

Dividing 17 by 20, we get 0.85.
Therefore, there would be 0.85 euro have the same value as 1 U.S. Dollar.
8/12 divide by 4 top and bottom
4/6 skipping this step
2/3 to get to here
26/x this is the end number we want
26/39 here it is multiplying the number making the number equal to the 2/3
