- The length of the car in her drawing is 6 cm.
- The scale is 3 cm : 2 m.
- Ivan draws with a relation 2 cm : 1 m.
First, we need to find the actual length of the car using Megan's ratio.
If 2 centimeters is equivalent to 1 actual meter of the car, 6 centimeters of drawing would be equal to
Therefore, the car is 4 meters long.
Now, using this information, we can find the length of the scale drawing of Ivan.
Therefore, Ivan's drawing is 8 centimeters long.

Step-by-step explanation:
Answer:

Each sequence has a difference of eight numbers so we add 8 numbers in each sequence
Let s and g represents the numbers of suits and gowns produced.
The number of zippers used is 2s+g.
The number of buttons used is 5s+8g.
In order to use all of the available zippers and buttons, we must have ...
- 2s + g = 171
- 5s + 8g = 576
Cramer's rule tells you the solution to the system
Is given by
- x = (bf-ey)/(bd-ea)
- y = (cd-fa)/(bd-ea)
Using this rule on the equations for zippers and buttons, we have
... s = (1·576 -8·171)/(1·5 -8·2) = -792/-11 = 72
... g = (171·5 -2·576)/-11 = -297/-11 = 27
72 suits and 27 gowns can be made from available zippers and buttons.
