The value of <em>x </em>in the equation, (3x + 30), is 10.
1 euro = 1.35261 USD
The Ruiz family will be able to exchange their euros for US dollar using the rate of $1.35 per 1 euro.
Use the general form:-
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre and r = radius
Here the radius = 1/2 * 6 = 3 so r^2 = 9 and we have the equation:-
(x + 4)^2 + (y - 2)^2 = 9 (answer)
You can say : 30/100% = 32/? ⇒ 32*100 /30 = 106.6 games :))
i hope this is helpful
have a nice day
