8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
just multiply 12 times 4. thats 48. so 48 divided by 4 is 12
The answer is A hope you get it right (:
You can use linear equations if something is being raised or decreased with the same linear function. Such as temperature or the amount of books that get sold.
1 cup = 0.25 quarts,
12+15+5 = 32 cups:
32 * .25 = 8 quarts
