1km = .621 miles
So......10 times this is about 6.21 miles
0.0612 rounded to the nearest thousandth is 0.061
Let x be the first integer....and we have....
x + (x + 1) + (x + 2) + (x + 3) = 106 simplify
4x + 6 = 106 subtract 6 from both sides
4x = 100 divide both sides by 4
x = 25
So.....the intrgers are 25, 26, 27 and 28

12p-7=-3p+8 add 3p to both sides add 7 to both sides
15p = 15 divide both sides by 15
p = 1
sqrt (81) = 9
sqrt(74) = about 8.6
sqrt(64) = 8
l -86 l + 45 =
86 + 45 =
131 ft
If your cost is greater than your sales, you nave no profit...in this case.....you lose 112 - 98 = $14
Assuming she didn't spend money on anything else but coffee....3 x $1.29 = $3.87
15km x 1 mile/.621 km = 9.315 mi
1L = .264 gallons
So 9.315mi / .264 gal = 35.28 mi/gal
