110 degrees :) because they are parallel lines so they’re vertical
Rate = A ratio that compares two quantities measured in different units.
Unit Rate = A rate in which the second quantity in the comparison is one unit.
Since the discount is 20%, we know that $24 is 80% or 4/5 of the original price of the shoes. Divide the $24 by 20%, and you get $6. Add that to $24, and you get the original shoe price: $30. You can verify by Multiply 30 by 80%, which comes out to the discount price-$24.
So if you have 30 oil, 24 photos, 21 sketches, the first thing I notice is that all of these numbers are divisible by 3. Since there are no specifications of how many rows for each category. You can divde the 30/10, 24/8, and 21/7 you would have 10 rows oil, 8 rows of photos, and 7 rows of sketches. In short, I believe your answer should be 3.
Hope this helps! Sorry if this explanation is unclear, please feel free to ask questions. <3
