move the 3 to the 12 and change it from pos to neg so 12-3=9
Mr. Abbot mowed 1/4 of his lawn.
His son mowed 3/7 of the lawn.
The first thing to do is get a common denominator, in this case a good one to use is 28. it has to be a number divisible by 4 and 7.
1/4=7/28
3/7=12/28
so now we can see that the son mowed more. now add these two numbers together to get how much they mowed in total
(7+12)/28=19/28 of the lawn is mowed.
that means 9/28 of the lawn still has to be mowed.
Answer:
$4911.45
Step-by-step explanation:
To find Megan's average daily balance, we first need to assume that the billing cycle begins at January 1st.
Now we know that there are 31 days in the month of January, we will use that as our basis.
20 days x 4805 = First 20 days of the billing cycle.
11 days 4805 + 300 = 21st day of the billing cycle.
31 days in the month
So now we simply add the first 20 days and the days after the 21st day and divide it by the number of days in the month since we're looking for the average.
(20 x 4805 + 11(4805+300))/31
(20 x 4805 + 11(5105))/31
(96100 + 56155)/31
152255/31
This then gives us:
$4911.45
