Thank you for posting your question here, to solve the compound inequality of 5x + 11 ≥ –9 and 10x – 3 ≤ 27 the answer is A which is " x ≥ –4 and x ≤ 3". Below is the solution:
5x + 11 ≥ -9 and 10x - 3
≤ 27<span>
5x ≥ -9 - 11 and 10x ≤ 27 + 3
5x ≥ -20 and 10x ≤ 30
x ≥ -20/5 and x ≤ 30/10
<span>x ≥ -4 and x ≤ 3</span></span>
Answer:
Reserved seats tickets = $20
General admission tickets = $12
Step-by-step explanation:
From the above question:
Let us represent
Reserved seats tickets = R
General admission tickets = G
Reserved seat tickets for a concert cost $8 more than general admission tickets. Hence,
R = G + 8
Five reserved seat tickets and 3 general admission tickets cost at total of $136. Hence,
5R + 3G = 136
So, we substitute G + 8 for R in the equation above
5(G + 8) + 3G = 136
5G + 40 + 3G = 136
5G + 3G = 136 - 40
8G = 96
Divide both sides by 8
8G/8 = 96/8
G = 12
Therefore the cost of one General admission ticket = $12
Since R = G + 8
R = $12 + $8
R = $20
Therefore, the cost of the reserved seats tickets = $20
Answer:
the domain of y = x is all real numbers.
c = $10 + $0.50s
Assuming you bought 10 songs; then
c = $10 + $0.50(10)
= $10 + $5
c = $15
Bear in mind that the $10 is only a one-time membership fee, so, any purchase of songs after your payment of the $10 will be computed by $0.50s.
