Answer: $22.50
Step-by-step explanation:
25% of 30 = 7.5
30 - 7.5 = 22.50
No, because since each pennant cost 18$ then 7 pennants should cost 126$. So for Ms. Lee to pay 146$ is not reasonable.
Answer:
- (-11.70, -2.05), (4.70, 5.10)
Step-by-step explanation:
<u>Given equations</u>
<u>Solving the first equation for x:</u>
- (x+5)(x+2)=65
- x^2 + 7x + 10 = 65
- x^2 + 7x - 55 = 0
- x = (-7 ± √(49+4*55))/2
- x = -11.70, x = 4.70
<u>Then solving for y:</u>
- y= 24/(-11.7) = -2.05
- y = 24/4.7 = 5.10
<u>Solution set: </u>
- (-11.70, -2.05), (4.70, 5.10)
