The value of expression b is eight times the value of expression a without evaluating expression a, determine what number belongs in the box in expression b. explain how you determined this question. expression a: 4×[(1.5+100.25)x3.65] expression b : ? ×[(1.5=100.25)x3.65]

The first thing we are going to do for this case is to write the following expression:
 Expression B = 8 * (Expression A)
 Substituting we have:
 Expression B = 8 * (4 × [(1.5 + 100.25) x3.65])
 Then, rewriting:
 Expression B = 32x [(1.5 + 100.25) x3.65]
 
 the number that belongs in the box in Expression B is:
 32

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.
