James has a collection of dimes and quarters. he has a total of 18 coins thay add up to 2.70. how many more dimes than quarters does he have?

Ok, so we know he has 18 coins of quarters and dimes.

Which all equal up to $2.70.

As I estimate, there could be 7 dimes and 8 quarters. But 8 + 7 = 15, so that means there are more than 7 dimes and less than 8 quarters-- but still equal all to the value of $2.70.

As I did my math, this is a very intruging problem and interesting problem. It isn't 6 dimes and 7 quarters cause that equals to $2.35.

I fillany found the answer by my little brother who also was interested with this question (who is smarter than me sadly), and I was quite surprised. So, the answer would be...

12 dimes = $1.20
6 quarters = $1.50

$1.20 + $1.50 = $2.70.

(Plus, this was so hard, thanks little bro)

So, 6 more dimes than quarters.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
