There are 13 students in Sara's class. I did this by using 8 = 3/5x, x being the total number of students. The answer is 13.33334 but you cant have half a student so it rounds down to 13.
also number 4 can be any positive number. This is because if you take one fourth of a negative number it will be more than if you doubled it. for example 1/4 of -4 is -1 which is more than -4 doubled which is -8

Leslie wrote this equation for the area of a parallelogram. 17.8h = 384.48. What is the height (h) of this parallelogram? A. 684

AleksAgata [21]

17.8h = 384.48 ,To find h we divide both sides by 17.8 (so that the h is alone. Keep in mind that the h=height)

17.8/17.8=h (1)
384.48/17.8=21.6

Therefore, h=21.6units
So B
