Jack used the Distributive Property
The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
= (45/60) euros
= ( 3/4) euros
= 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A".
I hope the procedure for
getting to the correct result is clear enough for you to understand. In future
you can use this procedure for solving similar problems.
R/9 = -21
Multiply by 9
r = -189
Answer:
-2/3
Step-by-step explanation:
in y=mx+b, m= the slope
and if you were graphing, you would put 2 on the y axis and use the rise over run strategy for the slope
hope this helped:)
