Answer:

x = (2 ± √10) / 3

Step-by-step explanation:

3x²=2(2x+1)

3x² - 4x -2 = 0 .. 2 roots: (-b ± √b² - 4ac) / 2a

a = 3, b = -4, c = -2

x = ((-(-4)) ± √(-4)² - 4x3x(-2)) / (2x3)

= (4 ± √16 + 24) / 6

= (4 ± √40) / 6

= (4 ± 2√10) /6

= (2 ± √10) / 3

yawa3891 [41]

Answer:

696 large bags of flour were packed.

Step-by-step explanation:

Let large bags of flour be 'y'

Let small bags of flour be 'x'. That is x=2040 (according to the question)

$(3 \times x) + (5 \times y) = 9600$

$(3 \times 2040) + ( 5 \times y) = 9600$

$(6120) + (5 \times x) = 9600$

$(5 \times x) = 9600 - 6120$

$(5 \times x) = 3480$

$x = 3480 \div 5$

$x = 696$
