How do i show my work for 26.45 divided by 126

Identify this conic section. x2 - y2 = 16 o line circle ellipse parabola hyperbola

Yvaries directly as x. y =90 when x=6. find y when x=13

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
