Raul tried to evaluate an expression step by step. 3 − ( − 5 ) − 7 = 3 + 5 − 7 step 1 = 3 + 2 step 2 = 5 step 3 = = = 3−(−5)−7 3+5−7 3+2 5 step 1 step 2 step 3

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
