Percentage of students that are girls in the class = 60%
Number of girls in the class = 18
Let us assume the total number of students in the class = x
Then
60% * x = 18
(60/100) * x = 18
6x/10 = 18
6x = 18 * 10
6x = 180
x = 180/6
= 30
So the total number of students in the class is 30.
Number of boys in the class = 30 - 18
= 12
So there are 12 boys in the class. I hope the procedure is simple enough for you to understand.
3x+4(-4x+4)=-75
Order of operations requires distribution first:
3x+ -16x+16=-75
Then add common terms:
-13x+16=-75
Subtract 16 from both sides:
-13x = -91
Divide by -13 from both sides:
x = 7
Answer:
(7, 63)
Step-by-step explanation:
X= 7 and Y=63
