A = 60 but b is unsolvable, plz update question it is wrong
Answer:
You have to describe what it is, like for example a quadrillateral or paralellogram.
Step-by-step explanation:
The exchange rate is 60:50 (us:euro)
if you have 70 euros, then x:70
60(x) : 70(50)
60x /60 : 3500/60
x = 58.33
seventy euro dollars = $ 58.33 on that particular day
hope this helps
