Solve the following equations. a. q + 35 = 78 b. 200 + x = 450 c. k – 68 = 72 d. 437 – m = 25

a) q + 35 = 78   (subtract 35 from 78)

   q = 43

b) 200 + x = 450 (subtract 200 from 450)

   x = 250

c) k - 68 = 72 (add 68)

   k = 140

d) 437 - m = 25 (you can do this in one step, but add m to other side or divide  everything by -1 to get m pos)

   m + 25 = 437 (subtract 25)

   m = 412

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

definitely a. the others have almost all data points on one side of the line.
