A box is a cuboid with dimesions 26cm by 15cm by 20cm all measured to the nearest centimetre. disc cases are cuboids which measure 1.6cm by 14.2cm by 19.3cm all measured to the nearest millimetre.

If the disc cases are stacked as shown, show that it may NOT be possible for 16 cases to fit in the box.

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
