Step-by-step explanation:
Remember that
so
Decompose the numbers 18 and 42 in prime factors
we know that
Find the least common multiple (LCM)
The LCM is
we need to find all multiples of 126 that are less than or equal 900.
therefore
7 times during the first 15 minutes
Answer:
Each of them had $49 at first.
Step-by-step explanation:
Given:
Cedric and Doug each had an equal amount of money.
Let the number of money they had at first be x
Cedric spent = $35
Doug spent = $28
Cedric Money left =
Doug Money left =
the ratio of Cedric money to Doug money was 2:3
Hence the expression can be made as;
Now by cross multiplication method we get;
Now we will use distributive property to elaborate the same;
Combining common terms we get;
Using Subtraction property we get;
Hence $49 they each had at first.
