I don’t understand? Can u put like a picture and I’ll try to answer through the comments
Step-by-step explanation:
There are 10 + 20 = 30 total students in the class.
Total marks for the class = 60 * 30 = 1800.
Total marks for the girls = 54 * 20 = 1080.
=> Total marks for the boys = 1800 - 1080 = 720.
Mean mark for the boys = 720 / 10 = 72.
The equation would be written as 8(x-3)
Hint: “the result” emphasizes parenthesis, so whenever you see that in a word problem, make sure to put parenthesis around whatever the problem is.
Hope this helps!
