1.what is the value of -3 1/3 divided by 1 1/4 expressed as a mixed number? 2.wally purchased a fan that was on sale for 4/9 of the original price. if the original price was $180, what was the price wally paid?

(1) Answer = - 2 2/3

(2)Answer : Price wally paid = $80

Step-by-step explanation:

(1)

We need to find, -3 1/3 ÷ 1 1/4

i.e - 10/3 ÷ 5/4

or -10/3  × 4/5

or -(10 ×4) / (3 ×5)

or -40/15

or -8/3

or -2 2/3   This is the answer

(2) Given, original price of fan = $180

And

Wally paid 4/9 of original price .

i.e Price wally paid = 4/9 * 180

 Price wally paid = $80

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
