Ok..So.. we will make this notation adult tickets= x and student tickets=y. It says that the number of student tickets was 2 times the number of adult tickets, so.. y=2x. x+y=408 (the total number)=> x+2x=408. 3x=408 => x=408/3 => x=136. (the number of adult tickets)
The answer for this question is C
If 9kg costs 12$, then a single kg costs around 1.3$
This is done with a simple proportion
9 : 12 = 1 : X
x = 12/9
x = 1.33
The answer is:
X int- 4
Y int- -12
Explanation:
You must subtract 12 from both sides
4x-6y-12=0
Add -6y to both sides
4x-12=y
Plus into y=mx+b
Y=4x-12
Hope this was helpful
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y) → (x, - y), hence
A(- 6, 2) → A'(- 6, - 2)
B(- 9, 1) → B'(- 9, - 1)
C(1, - 6) → C'(1, 6)
