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.
Answer:

Step-by-step explanation:
Answer: Substitution
Step-by-step explanation:
GIVEN:
y=3x
2x+4y=12
Then, 2x+4(3x)=12
-----------------------------------------
Substitution: replacing one variable in terms of another variable.
As we can see from the given aspects, y=3x, and the conclusion expression has no y instead of 3x. This means it represented y in terms of x, which fits the definition of substitution that replaces one variable.
Hope this helps!! :)
