Answer:
the equation representing total amount of blood donated is
.
Step-by-step explanation:
Total number of volunteers = 32
number of volunteers couldn't donate blood =
.
So Number of volunteers who donated blood can be calculated by subtracting number of volunteers couldn't donate blood from Total number of volunteers.
Framing in equation form we get;
So, the number of remaining volunteers who donated blood =
.
Each of these volunteers donated blood = 470 ml
Now Total Amount of Blood donated is equal to Amount each of these volunteers donated blood times the number of volunteers who donated blood.
Framing in the equation form we get;
total amount of blood donated milliliters = 
Hence the equation representing total amount of blood donated is
.
Answer:
(x²-2x)/(2x+6)
Step-by-step explanation:
When you are asked to divide two fractions just do keep-change-flip. Keep the first fraction, change the ÷ to x and flip the second fraction upside down. So the problem becomes ((x-2)/(x+3)) times (x/2). Then just multiply numerators and multiply denominators.

We know that
An ordered pair is used to locate a point on a coordinate grid.
The first number in an ordered pair is the
x-coordinate, and the second number in an ordered pair is the
y-coordinate.
In this problem, the ordered pair is

so
the x-coordinate is equal to

the y-coordinate is equal to

therefore
Rule N 1The y-value is

times the x-value
Rule N 2The y-value is

greater than the x-value
Both are possible because their solutions include the ordered pair listed
