We just have to multiply 20 by 10mm, which is 200mm. 100mm is equal to one centimeter, so the body length of the insect under the microscope is two centimeters.
The answer that I got is C=-6
X + Y = 50
X = Y + 6
X = 28
Y = 22
28 + 22 = 50
28 - 22 = 6 (28= 22 + 6)
There are 28 students in the larger class.
Hope this helps :)
