Mutually exclusive means two things that cannot happen simultaneously. John cannot eat 4 apples at a time. I hope that helps:)
We are given with two equations X + y = k and <span>x - y = k. to find the solution of the </span>system<span> of linear equations, we can use elimination by adding the equations to eliminate y. hence the third equation is 2x= 2k ; x = k, hence y is equal to zero. Answer is C</span>
Answer:
16
Step-by-step explanation:
The total profit is $93
He made a $45 profit selling hats
The question says he only sold t-shirts and hats
Since we are solving for the amount of t-shirts sold we subtract $45 from $93 and get $48 dollars earned from t-shirts
He makes $3 per t-shirt
We divide the amount per t-shirt by the total t-shirt money earned
This looks like: 48/3
We get 16 as our answer
