Step-by-step explanation:
If you add all the students subjects together you get a total of 41. Then if you add up the total of students who study physics, chemistry, and both you get 20. Then I put those numbers is a percentage calculator then boom you got your answer.
Any equation that has the same slope that’s not the exact same equation would be parallel to that line.
Hola,
no habla espanol muy bueno pero voy a tratar a ayudarlo. podemos simplificar 6/15; simplemente divide por 3. el resultado es 2/5, no 3/5. entonces, 6/15 no es equivelente al 3/5.
An equation to represent the relationship between miles driven (y) and gallons of gas (x) used is 
- Let the miles driven be y.
- Let the gallons of gas be x.
<u>Given the following data:</u>
Distance = 28 miles
To write an equation to represent the relationship between miles driven (y) and gallons of gas (x) used:
<h3>How to solve a word problem.</h3>
In this exercise, we would assign a variable to the parameters stated in the question in order to write an equation to represent the relationship between miles driven (y) and gallons of gas (x) used by Weston’s car during the trip.
Also, the amount of gas used up by a car is <u>directly proportional</u> to the distance traveled by the car. Mathematically, this is given by this expression:

Substituting the given parameters into the formula, we have;

<u>Note:</u> k is the constant of proportionality.
