To answer this, you will determine what fraction of the original rocks are silver by using the information about the other two colors.
If 2/3 of them area purple, than 1/3 are not.
If 3/4 of the remaining 1/3 is blue, than 3/4 x 1/3 = 3/12 of then are blue.
2/3 are purple, 3/12 of them are blue, the remaining is silver,
1 - 2/3 - 3/12
1 - 8/12 - 3/12 = 1/12
1/12 of the rocks are silver. If 3 are silver, write an equation that needs solved.
1/12r = 3
r = 36 rocks
There were 36 space rocks in total.
The weight of each pile yesterday will 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.
It is Given that Yesterday the ratio of seeds in these piles was 3:4.
Let 3x and 4x represent the seeds.
If the 2 pounds of seeds are added in the bigger pile, then
4x + 2
He also ate 1/4 pound from the smaller pile,
3x - 1/4
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 each pie will be
3x = 6 pound
4x = 8 pound
Hence, The weight of each pile yesterday would be 6 and 8 pounds.

Make sure that 8 and 4 are to the power
Answer:
-4,9 , -4,-1 , 4,-1 , 4,9
Step-by-step explanation:
The y-axis is straight up and if you move down on the and moving up 5 is 9 and moving down 5 is -1 and depending if it's on the right of left (negative or positive) the x-axis is (the 4) is postive or negative.
Answer would be: 201.7 degrees, Hope this helps :)
