a box full of packets weighs 33 kg . of the box weighs 1.5kg how many 350g packets does it hold? Pls help

90 packets

Step-by-step explanation:

Subtract the weight of the box.

33-1.5=31.5

There are 31.5kg of packets.

Convert it to g.

31500g

Divide it by the weight of one packet.

31500/350=90

The box holds 90 packets.

The box holds 90 packets.

Step-by-step explanation:

Subtracting the 1.5 kg box weight from the weight of the full box of packets yields 31.5 kg, which is the measure of the packets already in the box.

Dividing this 31.5 kg by (0.350 kg / packet) yields 90.

The box holds 90 packets.

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
