He sold all general admission tickets

Can prove using simultaneous equations

50x + 60y = $1050
x + y = 21 => y = 21-x

50x + 60(21-x) = 1050
50x + 1260 - 60x = 1050
-10x = 1050 - 1260
-10x = -210
x = -210/-10
x = 21

x + y = 21
21 + y = 21
y=0

Since he sold 21 general admission tickets and no VIP tickets

Can you show me how to find the answer to -9+2a<3a= ?
Monica [59]

Answer:

a > -9

Step-by-step explanation:

-9 + 2a < 3a

1. Add 9 to both sides

-9 + 2a + 9 < 3a + 9

2. Simplify

2a < 3a + 9

3. Subtract 3a from both sides

2a - 3a < 3a + 9 - 3a

4. Simplify

-a < 9

5. Multiply both sides by -1 (reverse the inequality)

(-a)(-1) > 9(-1)

6. Simplify

a > -9
