We have to choose which set of integers is included in ( -1, 3 ]. Integers that are included in this set are: 0, 1, 2, 3. Set number 2 is not included because -1 is not among those integers. Set number 3 is not included because it has numbers - 1 and 4. Set number 4 is not included because numbers - 2 and - 1 are not in the interval ( - 1 . 3]. Answer: (1) { 0, 1, 2, 3 }.<span> </span>
Go on a calculator and txt that and might get it
4.16 / 5.20 = 1 / x.....4.16 lbs to $ 5.20 = 1 lb to $x
cross multiply because this is a proportion
(4.16)(x) = (5.20)(1)
4.16x = 5.20
x = 5.20 / 4.16
x = 1.25 per lb <==
Miles using 19.5 gallons = 585 miles
Miles using 1 gallons
(585 / 19.5) * 1
30 miles / gallon
