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)

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

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

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

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

$(5 \times x) = 3480$

$x = 3480 \div 5$

$x = 696$

Apply the distributive property to factor out the greatest common factor. 18d+12 =18d+12=18, d, plus, 12, equals? (plz help quic

qaws [65]

Answer:

Answer is 6(3 d+2)

Step-by-step explanation:

It is given the expression as 18d+12

Let's find common factor by prime factoring the terms.

18 d =2*3*3*d

12= 2*2*3

Common factors for both terms are 2, 3.

So, G C F = 2*3=6

Take out 6 from both terms to factor further.

We do get 6(3 d+2)
