Answer:
No solution
Step-by-step explanation:
Rearrange into quadratic form: 3x² + 0x - 3 = 0
Quadratic formula: when <em>ax² + bx + c = 0: x = (-b ± √(b² - 4ac))/2a</em>
Plug in: x = 0 ± √(0 - 4*3*3))/2a
From this, we can conclude that this equation has no solution, as <em>0 - 4*3*3 will definitely be negative</em>, and <em>a negative number can not be square rooted</em>.
3 students = $48.76
1 student = 48.76 ÷ 3 = $16.25 (nearest hundredth)
Answer: 8 skates
Step-by-step explanation:
Given that:
Skate rental = $3
Let number of skates rented by cotters = x
Hence, amount paid by cotters = 3x
The Moores paid $6 more
Moores amount = 3x + 6
Combined amount paid = 42
3x + 3x + 6 = 42
6x + 6 = 42
6x = 42 - 6
6x = 36
x = 36 / 6
x = 6
Hence, amount spent by the Moore's:
3x + 6
3(6) + 6 = 18 + 6 = $24
Cost per skate rental = $3
Hence x number of skates rented by the Moore's = $24 / 3 = 8 skates
