Answer:
The equation that represents the relationship between 'y' the total points, and 'x' the number of movies is option A;
A y = 3·x
Step-by-step explanation:
The information required in the question is an equation that represents the the relationship between the number of movie attended and the total number of points Marcy has given that she earns a fixed amount of points for attending each movie
The number of points she will earn for attending each movie = 3 points
The total number of points she will earn 'y' when she attends 'x' number of movies is given as follows;
y = 3 + 3 + 3 + ... + 3, 'x' number of times, and we can write
Therefore the equation that represents the relationship between 'y' the total points, and 'x' the number of movies is y = 3·x.

Answer:
The expression represents the price you paid per gallon is:
- Price paid per gallon =
Step-by-step explanation:
To identify the expression is right, I'll show you with an example: suppose that you paid $56 buying 7 gallons of gas, now you can replace those values in the expression I gave you:
- Price paid per gallon =
- Price paid per gallon =
- Price paid per gallon = 8
And you can check this value by multiplying the price paid by the gallon and the number of gallons, which you obtain the number of dollars you spent:
- <u>Number of dollars (d) = 8 * $7 = $56 </u>
