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
To get percentage u take the percent u are trying find and divide it by 100 like 98percent and u get .98 then u would multiply .98 by 192 and u get 188.16 u do the same with the next two and u get 66.34 , 39.48
Answer:
Option 4 (±1, ±1/3, ±3, ±9) is the correct option.
Step-by-step explanation:
The given expression is 
We have to find the possible rational zeros for the function.
So by the rational zero theorem factors will be
=±(Factors of constant term 9)/±factors of coefficient of 
=±(Factors of 9)/±(Factors of 3)
=±(1, 3, 9)/±(1, 3)
=±(1, 3, 9, 1/3)
So option 4 is the correct answer.
Answer:
y = 1/4x - 1/2
Step-by-step explanation:
-4y = -x + 2 : Divide both sides by -4
y = 1/4x - 2/4 : Reduce to lowest terms
y = 1/4x - 1/2
