Hmmmm...... Are you a 6th grader? I remember doing these in 6th grade.
1st. Try to make x by itself. Divide 12 on each side.
After it will look like this
x=12
Answer:
14 minutes below or 6 minutes above
Step-by-step explanation:
Let's say Sophia's time was 10 minutes WORSE
4 minutes below average- 10 minutes= 14 minutes below average
Let's say Sophia's time was ten minutes BETTER
4 minutes below average + 10 minutes= 6 minutes above average.
Hope this helps!
