The italian size of a suit jacket is n centimeters, where n is the linear distance between the armpits. the american size of a suit jacket is 2.5p centimeters, where 2.5p is twice the linear distance between the armpits. if, for a particular jacket, n = p + 10, which of the following is closest to the value of n? (one inch is approximately 2.54 centimeters.)
a) 36b) 47c) 58d) 65e) 72

  B)  47

Step-by-step explanation:

If we assume the 2.5P is more accurately 2.54P, then we have two relations between N and P:

Solving the second for P gives ...

   P = N -10

and substituting that into the first gives ...

  2.54(N -10) = 2N

  0.54N -25.4 = 0 . . . . . . subtract 2N

  N -47.037... = 0 . . . . . . .divide by 0.54

  N ≈ 47 . . . . . . . . . . . . . . add 47.037... and round

The closest value of N is 47.

Comment on the problem

If you take the problem at face value, you compute N=50. The closest offered answer is still 47. In this scenario, the relationship between inches and centimeters is irrelevant, as there are no inches anywhere in the problem.

there is no picture

step-by-step explanation:

put up a picture so people can you

so, converting firstly the mixed fractions to improper fractions and then "adding".
