Ответ:
So we know that 18 students equal to 22.5. And we are looking for the anwser what 100% of students is.
SO:
x students - 100%
(22 + 1/2)x =18×100
(22 + 1/2) can be represented as just 25.5
-//- = 1800
we need to divide bot sides by 25.5
x = 1800 / 25.5
... x = 80
Ответ:
C
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
y + y + 54 = 180
2y + 54 = 180 ( subtract 54 from both sides )
2y = 126 ( divide both sides by 2 )
y = 63° → C
