Krishaun has $5, $10, and $20 coins worth a total of $560. She has the same number of $5 coins as $10 coins and the same number of $10 coins as $20 coins. How many $20 coins does Krishaun have?

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
