Answer:
Step-by-step explanation:
R=x/7 let's say R is what Ryan earned, and so he earns x dollars every seven days
L=2(R)
L=2(x/7)Let's say L is what Lee earned, she earned twice as much as Ryan so 2(x/7)
Total=2(x/7)+x/7
Total=3(x/7) the total earnings is the sum of x/7 and 2x/7 is 3x/7
Consider the expression
Use main properties for powers:
1.
2.
3.
Then
The result in scientific notation is
The result as a decimal is
Sod=1*1
to cover =30*14
to cover=420
to cover divided by one piece
=420/1
=420 pieces
