They both get their cars washed on every 60th day.
You can solve this equation by finding the lcm (least common multiple):
15 30 45 60 75 90 105
20 40 60 80 100
The lowest common multiple is 60 as it is the first multiple the two have in common.
So, in sixty days, they’ll both get their car washed again
The Answer should be either x=15 or x=5 I got both.
The answer to this equation is 13ft squared
You would subtract 3/8-2/8, which equals 1/8. For drawing a model draw fraction strips to help.
