She spent $7.44 because 3.28 + 1.27 + 0.56 + 2.33 = 7.44
Adult ticket (a) = $5
Child ticket (c) = $2
785 tickets = $3280
a + c = 785 tickets
5a + 2c = $3280
c = 215 child tickets
a = 570 adult tickets
570 + 215 = 785 tickets
5(570) + 2(215) = $3280
There were 215 child tickets sold on Saturday
Answer: x=1
Step-by-step explanation:
You need to open up the parenthesis so you multiply every term inside the parenthesis by -7.
1. -7x + 14 + 1 = 15 -7x
2. Combine like terms -7x + 15 = 15-7x
The two sides of the equation are the same so that means that x=1
G(F(2))
So f would be x
-(2x+1)-2 you slove it and get you answer and plug the answer back into the equation above as x
-(2(answer)+1)-2
Hope this helps
