Question

Help, For each equation, use guess-check-and-improve to approximate a
solution to the nearest tenth: 3n + 8 = 26
a. 4.0 c. 7.0
b. 6.0 d. 5.0

Answer 1

Answer:

B) 6

Step-by-step explanation:

3(6) + 8 = 26

18 + 8 = 26

26 = 26

I don't know that method they are referring to. Seems pointless.

Typically, you would just set that equation up like:

3n + 8 = 26

    - 8      -8

3n = 18

3n/3 = 18/3

n = 6
