Answer: 5
Step-by-step explanation: 5.07 rounds to 5
0.81 rounds to 1
so the best estimate for 5.07 x 0.81 = 5(1) = 5.......ANS
3.14 + 0.67 + 2.45 + 1.14 = 7.40
The students have $7.40 in total.
1hr = 60minutes
60min + 45 min = 105
4545÷105 = 47,7225 miles
Hey!
It says that it is the sum of 3 consecutive odd integers right?
So then we give these numbers some variables to work with like so...
x = 1st number
x + 2 = 2nd number
x + 4 = 3rd number
now set all of them equal to 207
x + x + 2 + x + 4 = 207
3x + 6 = 207
3x = 201
<u>x = 67</u><u /> <u>x + 2 = 69</u><u /> <u /><u /> <u>x + 4 = 71
