(melanie has 230 coins in her collection- number of european and non-european coins)and now has 180 european coins. write an equation to determine the number of non-european coins, e, if melanie has t total coins figure/find the non-european coins and identify the constant of proportionality. pls show work you: /

Total number of coins(including European and non European coins) =230

Number of European coins = 180

Let the number of non European coins be = E

T is the total coins or T =230

The equation to determine non European coins is

Solving this we get

hence, E = 50

true? is that what you're asking or do you mean something else?

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
