B + 24 + 7b + 4b = 180
12b + 24 = 180
12b = 156
b = 13
He would travel 67 1/2 miles in an hour.
Okay so the first thing we should do here is round 5.29 rounds to 5.30 3.59 rounds to 3.60 and 4.79 rounds to 4.80 now add all of those up youll get 13.7 you can round that to 14 so samanthas estimate is accurate
Answer:
Range is 32
Step-by-step explanation:
11,12,13,17,17,17,17,19,20,32,43
43-11 = 32
$3, $1, $5, $2, $3, $9, $1 = $24 - $1 = $23 - $1 = $22.
$22 is the estimation of the bill when all of the amounts are rounded to the nearest dollar. The estimation is greater than the total bill which is 23 cents less than the estimation. The total on the register is reasonable and accurate.
