Answer:
41 miles
Step-by-step explanation:
the company is saying they will round the number of miles, and charge you that number
when rounding 40.8, you round up to 41
1,2,3,4 rounds down to 0
5,6,7,8,9 rounds up to the next 0 up
Answer:
We have 7.2 / a = 6 / -4;
Then a = ( - 4 x 7.2 ) / 6;
a = - 28.8 / 6;
a = - 4.8;
Step-by-step explanation:
Bill = 4b + 2.
Ron = 8b - 5.
Bill + Ron = (4b + 2) + (8b - 5).
= 4b + 8b + 2 - 5.
= 12b - 3.
That's the expression for the total number of blocks used by both Bill and Ron.
