(01.02 mc) evaluate the following expression using the values given: find 2x − 3y − z if x = −2, y = 3, and z = −2 −11 11 −15 15

2x − 3y − z 
 x = −2,
 y = 3,
 z = −2
 What we must do is replace the values given in the equation. We have then replacing:
 2*(-2) - 3*(3) - (-2) = -11
 The answer is -11

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
