Answer:
a. 1/10 b. did not understand question
Step-by-step explanation:
It is as simple as two fifths of one fourth. (2/5) * (1/4)= 1 tenth.
Answer:
Both proportions are equivalent.
Step-by-step explanation:
We have been given two proportions 
and 
. We are asked to find why the solutions to our given proportions are equal.
We can solve proportions by cross multiplying them.
After cross multiplying our both proportions we will get same equation that is:
Since we get same equation after cross multiplying both proportions, therefore, the solutions to the given proportions would be same.
2x+3y= -17
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x.
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to:
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you:
-15y=85
4y= -8
You add them top numbers by the bottom and get:
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one.
5x + 2(-7) = -4
5x -14 = -4
5x = 10
x = 2
So the answer is (2,-7) or x=2 and y=-7
