Question

HELP MEDAL AND FAN I NEED THIS TO BE EXPLAINED TO ME I AM LOST ON THIS PROBLEM!

Answer 1

Yuri solved the equation below incorrectly. Explain the step where he went wrong.

b over fifteen minus one equals twenty-nine

Step 1: b over fifteen minus one plus one equals twenty-nine plus one
Step 2: b over fifteen equals thirty
Step 3: b over fifteen divided by fifteen equals thirty divided by fifteen
Step 4: b equals two

Answer 2

\[\frac{b}{15}-1 = 29\]
\[\frac{b}{15}=30\]
how would you get rid of the 15?

Answer 3

dividing by 2??

Answer 4

no. just like you add to get rid of a minus, or subtract to get rid of the plus. you will want to do the opposite operation.
you could look at it like this, if it would help:
\[b\div15=30\]

Answer 5

Answer 6

right!
