Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of
, so the snow melted in x hours will be
.
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:

To find the depth of snow after 3 hours we will substitute
in our expression.



Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.
Answer:
63 = 1 x 63, 3 x 21, or 7 x 9. Factors of 63: 1, 3, 7, 9, 21, 63. Prime factorization: 63 = 3 x 3 x 7, which can also be written 63 = 3² x 7.
