M(n+r)=s solve for n. Show two methods.
Serga [27]

Answer:

  1. n = (s/m) -r
  2. n = (s -mr)/m

Step-by-step explanation:

1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.

  m(n+r) = s . . . given

  n +r = s/m . . . divide by m

  n = (s/m) -r . . . subtract r

__

2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.

  m(n+r) = s

  mn +mr = s . . . eliminate parentheses

  mn = s -mr . . . subtract the added term

  n = (s -mr)/m . . . divide by the coefficient of n

inna [77]

Answer:

6

Step-by-step explanation:

I just learned about this yesterday. The line inside of the box is the median. The left side of the box, on the number 2, is the lower quartile. The dot on the line to the left, outside of the box, is above the smallest value. The right side of the box is the upper quartile. The line outside of the box on the right is the highest value. Hope this helps!
