Mrs. O'Neill has 9 times as many markers as colored pencils. The total number of markers ans colored pencils is 110. How many co lored pencils does Mrs. O'Neill have?
2 answers:
So if x is coloured pencils, then we can say that 9x + x = 110. This means that 10x is 110, and if we divide by 10, we get x is 11, which is the amount of coloured pencils. Hope this helps!
M = 9p m + p = 110 9p + p = 110 10p = 110 p = 110/10 p = 11 <=== there are 11 colored pencils m + p = 110 m + 11 = 110 m = 110 - 11 m = 99 <== there are 99 markers
