0.66666 that’s the answer
Answer:
Adults= 110
Children= 340
Step-by-step explanation:
Given data
let adults be x
and children be y
x+y= 450----------1
2x+y=680---------2
from 1
x= 450-y
put this in 2
2(450-y)=680
900-2y=680
900-680=2y
220=2y
y= 220/2
y= 110
x+110= 450
x= 450-110
x=340
(Mass) 2160g (Divided by) / (Volume) 240cm (Equals) = 9 (Density)
I think you just do 133/4 -2 unless I’m mistaken
Well to find out X, you have to do the opposite to what it's asking to each side. So 11=x-4
+4 onto the 11 and + 4 on to the -4 which means you just have 15=X
