The <u>correct answer</u> is:
The scale drawing is larger.
Explanation:
A scale for a scale drawing is written as a ratio in the form
(scale size):(actual size).
For example, on a map you may have a scale that says 1 in: 2 mi. This means that 1 inch on the scale is equal to 2 miles on the map.
The scale for this problem is 10 cm: 1 mm. This means that 10 cm on the scale drawing represents 1 mm on the actual object.
10 cm is larger than 1 mm, so the scale drawing is larger.
Answer:
I believe it's 22/15
Step-by-step explanation:
17x -6 + 3x - 5 = 1x + 11 + 4x first you add the 17x and 3x and 1x and the 4x
which it would be: 20x - 6 -5 = 5x + 11;
20x - 11 = 5x + 11,
-5 -5
15x - 11 = 11
+11 +11
15x = 22
15 15 Divide
x = 22/15
Hope my answer has helped you if not i'm sorry.
