Thomas found a board in his dad's garage. He cut off 15 in. Then he cut the remaining board into 3 equal pieces. Each piece is now 25 in long. How long was the board before he cut it? What strategy would be best to solve this problem? 9. Make a Model or Diagram B. Work Backwards 2. Guess, Check, and Revise D. Look for a Pattern​

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

yes i do see that. i say this because i am doing my very best in high school so i can get a scholarship and credits.
