Nancy has a 3.5-pound bag of birdseed. She uses 3/4 of the bag to fill a bird feeder in her garden. Then, she puts 0.25 pounds i
AnnyKZ [126]

Answer:

0.625lb bag of bird seeds

Step-by-step explanation:

She starts with a 3.5 lb bag,

Then she uses 3/4 of the bag, so find the remaining amount in the bag, which would be 1/4 of the original weight;

1/4 * 3.5

= 1/4 * 7/2

= 7/8

Then she removes 0.25 lbs of weight, hence take away 0.25 (the amount removed) from 7/8 (the current weight of the bag).

7/8 - 0.25

= 7/8 - 1/4

= 7/8 - 2/8

= 5/8

So she has a 5/8lb bag of bird seeds or a 0.625lb bag.

GenaCL600 [577]

Begin by factoring 2 out of   2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0.  2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2.  The equation is true for these two x-values.

Nate's package is 8 kilograms. This is because, if there are 1,000 grams in 1 kilogram, 8,000/ 1,000= 8 Therefore, the mass of his package is 8 kilograms.

Have a Merry Christmas!
