<u><em>Tyrell started with $541.</em></u>
First you must know the total amount of money spent on the games. For that Tyrell bought 6 video games this summer and each game cost 27 dollars. So to calculate the amount spent, the number of games purchased must be multiplied by the price of each one:
6 video games* 27 dollars each game= 162 dollars
So Tyrell spends 162 dollars.
On the other hand, you know that Tyrell had 379 dollars left after he bought the video games. This indicates that after spending $ 162 on video games, there were $ 379 left over. To know the amount of money that Tyrell had, you must add the amount spent on games and the money that was left over:
162 dollars + 379 dollars= 541 dollars
So, <u><em>Tyrell started with $541.</em></u>
Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.
Subtract 9a from both sides to get a on the left side of the equation.
5 + 5a = -5
Subtract 5 from both sides of the equation to isolate the term with a.
5a = -10
Divide both sides of the equation by 5 to solve for a.
a = -2
In mathematical modeling<span>, </span>statistical modeling<span> and </span>experimental sciences<span>, the values of </span>dependent variables<span> depend on the values of </span>independent variables<span>. The dependent variables represent the output or outcome whose variation is being studied. The independent variables represent inputs or causes, i.e., potential reasons for variation or, in the experimental setting, the variable controlled by the experimenter. Models and experiments test or determine the effects that the independent variables have on the dependent variables. Sometimes, independent variables may be included for other reasons, such as for their potential </span>confounding<span> effect, without a wish to test their effect directly.</span>
