The chairs in a school were arranged in 15 rows with 28 chairs in each row if these chairs were rearranged into rows of 20 how many rows of chairs would there be

21 rows

Step-by-step explanation:

First find out the number of chairs that are currently in the school.

= 15 rows  * 28 chairs

= 420 chairs

If 420 chairs were to be arranged in rows of 20, the number of rows would therefore be:

= 420 / 20 per row

= 21 rows

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265
