The weight of the each pile yesterday would be 6 and 8 pounds.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given;
Yesterday the ratio of seeds in these piles was 3:4.
Let it be 3x and 4x.
If the 2 pounds of seeds is added in the bigger pile, then it become
4x + 2
He also ate 1/4 pound from the smaller pile, then
3x - 1/4
Now the quantities of seeds in those piles is in the ratio of 5:16.
So, 4x + 2 = 5x
3x - 1/4 = 16x
Solve;
So, 4x + 2 = 5x
2 = 5x - 4x
x = 2
The weight of the each pie would be
3x = 6 pound
4x = 8 pound
Hence, The weight of the each pile yesterday would be 6 and 8 pounds.

Answer:
( 1 + x) ( 7 - x)
Step-by-step explanation:
Here's what I did
16 - ( x - 3)^2....expand this
16 - (x² + 6x + 9).....after exanding
16 - 9 + 6x - x²......like terms together
7 + 6x - x² ......rearrange
-x² + 6x + 7......look for the product, sum and factors
( 1 + x) ( 7 - x)
Answer:
There are 24 outcomes in the sample space.
Step-by-step explanation:
Suppose that we have some events, such that each one of these events has a given number of outcomes.
If we have an experiment where we perform all of these events, the total number of possible outcomes is equal to the product between the number of outcomes for each one of the events.
Let's apply this to our case.
Here we have two events:
Rolling a standard number cube: 6 outcomes
Spinning a spinner with 4 equal sections: there are 4 outcomes.
Then the total number of outcomes in the sample space is the product:
C = 6*4 = 24 outcomes.
There are 24 outcomes in the sample space.
Answer:
240
Step-by-step explanation:
1) First you set up a proportion.
2) You do 12/60=x/1,200.
3) You cross multiply and do 12x1,200. Your answer is 14400.
4) Then you do 14400/60=240
