Your friend swims on the school team. in her first four races, her times are 26.3, 28.4, 25.6, and 29.1 seconds. which time listed for her next race would make the range larger? a-25.2b-26.1c-28.0d-29.1

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

it is 28 degrees colder in detroit than philadelphia.
