Answer:
Solving for one variable and using that solution to find the other variable.
Step-by-step explanation:
So if i said y=3x-2 with another equation like 12y+4= -16
you would plug in y to the second equation making it 12(3x-2)+4=-16 then you would solve for x. I hope this helps
You can determine if two numbers are equal if they have the same value. (4 are 4 are equal) (4 and 5 are not equal). You can determine if two expressions are equal by solving them. If the answers are of an equal value, they are equal. (4+5 and 6+3 are equal because they both work out to be 9) (4+5 and 5+5 are not equal because they work out to be 9 and 10.)

The product of 4√27 and 5√3 in simplest form is 180. Thus, the result obtained is a rational number
<h3>Surd operation</h3>
Surd multiplication can be carried out as illustrated below:
a√b × c√d = (a × c)√(b × d)
<h3>How to determine the product of 4√27 and 5√3</h3>
The product of 4√27 and 5√3 can obtained as illustrated below:
a√b × c√d = (a × c)√(b × d)
4√27 × 5√3 = (4 × 5)√(27 × 3)
4√27 × 5√3 = 20√81
But
√81 = 9
Thus,
4√27 × 5√3 = 20 × 9
4√27 × 5√3 = 180
Therefore, the product of 4√27 and 5√3 is 180
<h3>What are rational numbers?</h3>
These are number that are expressed as a ratio of two integers inwhich the denominator is not equal to zero
Considering that the product of 4√27 and 5√3 is 180, we can thus say that 180 is a rational number since it can be written as 180 : 1 (or 180 / 1)
Therefore, was can conclude that the result obtained from the product of 4√27 and 5√3 is a rational number

Thus, the values corresponding to the function and constraints will be:
Objective Function:
Constraints:
We begin by defining the variables. Let call:
X = of servings of dried apricots
Y= of servings of dried dates
For apricots, there are 3 servings in one pound. This means that the cost per serving is $9.99/3 = $3.33. The cost for X:
For dates, there are 4 servings per pound. This means that the cost per serving is $7.99/4=$2.00. The cost for Y:
The total cost would be:
Product must contain at least 4700mg of potassium
So now with the equations set it is possible to see that the desired values are between 9400 and 4700. Then using the critical points X=0, Y=0 for the two given equations. This will inform the points of interest for X and Y if this analysis is needed for the exercise.

Answer:
900 meters
Step-by-step explanation:
There are about 3 feet in a meter, so to find the answer you have to add up all the meters he swam and then multiply it by that.
So the equations will be: 100+200=300, 300x3=900.
Hope you get an A! <3
