Answer:
Step-by-step explanation:
In order to solve for x, she had to first subtract 6 on both sides of the equation. Then divide by 5 on both sides of he equation. After the division part, she was able to successfully isolate x.
The equation she had to solve was (C) 5x+6=21
First step: Subtracting 6 on both sides of equation resulted in
5x = 15
Second step: Dividing both sides of the equation by 5 resulted in
x = 3
There is no polygon there
16= 6 ones or 16 ones
817= 8 hundreds and 7 ones or 17 ones
Hope this helps! :D
