At 6 p.m., the temperature in Phoenix AZ, t is the same as the temperature in Tucson, AZ.By 9 pm the temperature in phoenix has dropped 2 degrees and in tucson it has dropped 4 degrees .By 11 pm the temperature in Phoenix has dropped another 3 degrees represent each city's temperature at 11 pm with an algebraic expression and bar model

Answer 1

Explanation:

Let the temperature of Phoenix be x

And temperature of Tucson be y.

So, the algebraic representation of temperatures in each city can be given as :

At 6 p.m

temperature of Phoenix = temperature of Tucson

i.e x = y

At 9 p.m

temperature of Phoenix = x - 2 {temperature in phoenix has dropped 2 degrees}

temperature of Tucson = y - 4 {temperature in Tucson dropped 4 degrees}

At 11 p.m

temperature of Phoenix = (x - 2) - 3 = x - 5 {temperature in phoenix has dropped another 3 degrees}

temperature of Tucson = (y - 4)
