A package of pens cost $1.09. Milio's work to find the unit price of the pack is shown below pens
$19€ - 3160
7-8-$1.09
7 - $7 34
Where did Mill make his first error?
He assumed the pens are equally priced.
He wrote the une rate incorrectly
* He made a piace value error when dividing
He multiplied instead of doviding

What are the solutions of the equation? 5z^2 + 9z - 2 = 0 a. 1, -2 b. 1, 2 c. 1/5, -2 d. 1/5, 2

The equation of a parabola is given. y=18x2+4x+20 what are the coordinates of the focus of the parabola?

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
