Step-by-step explanation:

2) Let 't' be the temperature

t < 7

Height be 'h'

h >= 42

Cos be represented by 'c'

c >= 125

3) Distributive property: a*(b +c) =(a*b) + (b*c)

2(5a + 3b) + 5a  +2b = 2*5a + 2*3b + 5a + 2b

                                   = 10a + 6b + 5a + 2b

                                  = 10a + 5a + 6b + 2b   {Combine like terms}

                                  = 15a + 8b

6y + 2(3x + 5) + 2y + 3 = 6y + 2*3x + 2*5 + 2y + 3

                                     = 6y + 6x + 10 + 2y + 3

                                     = 6y  + 2y + 10 +3 + 6x

                                      = 8y + 13 + 6x

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
