The answer to your question: the ratio of 4 months that have 30 days is ✨3 to 1✨
15 + 2x - 4 = 9x + 11 - 7x
2x + 11 = 2x + 11
always true
2x + 3(4x - 1) = 2(5x + 3) + 4x
2x + 12x - 3 = 10x + 6 + 4x
14x - 3 = 14x + 6
never true
Answer:
2. 4a+2c = 5000
4. a + c = 1600
Step-by-step explanation:
400 children and 600 adults bought tickets.
Step-by-step explanation:
Given,
Cost of one child ticket = $14
Cost of one adult ticket = $32
Total attendance = 1000
Revenue generated = $24800
Let,
x be the number of children.
y be the number of adults.
According to given statement;
x+y=1000 Eqn 1
14x+32y=24800 Eqn 2
Multiplying Eqn 1 by 14

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 18

Putting y=800 in Eqn 1

400 children and 600 adults bought tickets.
