A traffic engineer interested in safety research wanted to know the factors that influence road rage. The outcome measure was whether road rage was present (1 = yes, 0 = no). The predictor variables were

X =65 degrees

Step-by-step explanation:145=(2x+15)

grouping like terms ,the +15 crosses the equal to and turns into -15 and attaches itself to 145.            145-15=2x

                                                   130=2x

if 2x =130 then x will be = 130/2=2x/2

                                             65=x
