Answer:
y=10
Step-by-step explanation:
10^2-100=0
100-100=0
0=0
A) x² + y² = 327
B) x * y = 101
Solving equation B for y²
B) y² = 10,201 / x²
Substituting this into equation A)
x² + 10,201 / x² = 327
x^4 + 10,201 = 327x²
x^4 -327x² + 10,201 = 0
Using the quartic equation calculator: http://www.1728.org/quartic.htm
x1 = 17.090169943749476
x2 = 5.909830056250525
x1 * x2 = 101
x1 + x2 = 23
The answer is 60 bc -3 x -4 is 12, and 12x5 is 60
Given:
1 Van and 4 buses filled with 195 students.
1 Van and 5 buses filled with 241 students.
Let x and y be the number of students in Van and number of students in bus.

Subtract equation (1) from equation (2)

Substitute y=46 in equation (1)

Number of students that van can carry is 11.
Number of students that bus can carry is 46
