You have to start with the parenthesis. 140-68=72. (remember to use pemdas parenthesis, exponent, multiplication, division, addition, and subtraction. Then you do 32-72/9=24. 240/8=30. 30-24=6. 6 is the answer.

Answer: People 18 and over are considered adults
Because more than or equal to 18
Good Luck!
I'm not sure what that last string of equalities is, but I think it is Mandy's work. Notice the ratio pattern that she begins with for the first three numbers, it's the output (y) value divided by the input (x) value. Then on the last ratio, she switches the two and divides the input (x) value by the output (y) value. Because of this, she thinks that the last term has a ratio of 1/5, while the others have a ratio of 5. She is incorrect because her common ratio is output divided by input, which is actually 5 for the last term (50/10).
Answer:
x = -26.3746, 11.3746
Step-by-step explanation:
Easiest and fastest way to solve for <em>x</em> is to graph x² + 15x - 300 and analyze where the graph crosses the x-axis.
Alternatively, you can use the Quadratic Formula to help solve for <em>x</em>.
