Subtract 5 from me then add 2. If you subtract 10 and then add 3, you get 15. What number am I

You are 25

Step-by-step explanation:

This problem is a word problem that requires algebra notation, actually, we are meant to convert this word problem to mathematical expression then solve.

We proceed in a stepwise manner

let say what I have is x

1. Subtract 5 from me

  (x-5)

2. Then add 2

    (x-5)+2

3.  If you subtract 10

      (x-5)+2-10

4.  And then add 3

    (x-5)+2-10+3

5.  you get 15

   (x-5)+2-10+3=15

what am I is the question we need to answer, we do this by solving for x

x-5+2-10+3=15

x-15+5=15

x-10=15

x=15+10

x=25

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
