Let the number of pages read on day 1 be = x
Then on day 2 he read twice the pages from day one, it is = 2x
On 3rd day he read 6 pages less than 1st day, it is = x-6
Total pages are = 458
The equation becomes: 
So on the third day, Aiden read 
pages.
Answer:
Kayla sold 90 boxes of cookies.
Step-by-step explanation:
let's have X be the number of boxes Kayla sold.
x⇒100%
18⇒20%
Find x,
x=100/20 × 18
x=90
17x+3y+5 if you just want to add common factors
W=9ft.
since the with is 9 that means the length is 27.then add up the sides to get the perimeter. 9+9+27+27=72
-5x≤40 would be the answer
