25.) Solve the compound inequality.
1 answer:
The right answer is Option C: x< -5 or x>2
Step-by-step explanation:
Given inequalities are;
2x – 2 < –12 or 2x + 3 > 7
We will solve first inequality;
2x – 2 < –12
Adding 2 on both sides;
Dividing both sides by 2
Solving the second inequality
2x + 3 > 7
Subtracting 3 from both sides
Dividing both sides by 2
Therefore;
x< -5 or x>2
The right answer is Option C: x< -5 or x>2

Answer:
To raise exactly $240, the charity needs to sell 20 snacks.
Step-by-step explanation:
Let
s = number of seats sold
y = number of snacks sold
Seats cost $24 each, then s seats cost $24s.
Snacks cost an additional $6 each, then y snacks cost $6y.
In total, s seats and y snacks cost $(24s+6y).
The charity needs to raise $240 to consider this event a success, so
If 5 seats are sold, then
To raise exactly $240, the charity needs to sell 20 snacks.
To solve this problem graphically, plot the graph of the line and find on this line point with s-coordinate 5. This is exactly point (5,20), so the charity needs to sell 20 snacks.
