How do I solve question 5?
Nezavi [6.7K]
A) x^2 + y^2 = 80
B) x * y = 12

What is x^2 -y^2?
B) x * y = 12
So y = 12 / x
A) x^2 + (12/x)^2 = 80
x^2 + (12/x)^2 = 80
x^2 + (144/x^2) = 80
Multiplying each side by x^2
x^4 + 144 = 80x^2
x^4 -80x^2 + 144 = 0
X = 1.355 (found by trial and error)
Y = <span> <span> <span> 8.85608</span></span></span> (found by trial and error)

Lee Middle School orders 15 textbooks for every 12 students. The table shows how many textbooks the school orders for certain nu
Mariulka [41]

Answer: 90 textbooks


Step-by-step explanation:

everytime you multiply the number of students you multiply the books by the same number. to find how many times 72 was multiplied you divide it by 12.

72 ÷ 12 = 6

then multiply the original number of books (15) by 6.

15 * 6 = 90

so for every 72 students the school orders 90 textbooks
