I'm having trouble seeing but I think it's the one in the bottom left
Seven is greater than 24/4, which when simplified becomes 6.
1. 2x²-3x²-3x+5x+1-2=-x²+2x-1
2.3x²+5x-2x+6-1=3x²+3x+5
3.-7n²-5n²+4n+6n+3+1=-13n²+10n+4
I think these are the answers if not I'm sorry
Answer:
350 students
Step-by-step explanation:
Let:
a = number of adults attending
s = number of students attending
a + s = 950 (1) (given)
9a + 6.5s = 7675 (2) (cost per adult * number of adults + cost per student * number of students = total amount spent)
Looking for s. Multiply (1) by 9 then subtract eq (2), this will eliminate the variable a:
(1) 9a + 9s = 8550
- (2) 9a + 6.5s = 7675
-------------------------------
0a + 2.5s = 875
s = 875/2.5 = 350 students
The answer is the second one
