Mathematics
1 answer:
mr Goodwill [35]3 years ago
7 0

Answer:

  20/81

Step-by-step explanation:

Without parentheses, it is hard to tell what you are dividing. We assume you want ...

  (4/9)/(9/5)

Then ...

\displaystyle\frac{\left(\frac{4}{9}\right)}{\left(\frac{9}{5}\right)}=\frac{4}{9}\cdot\frac{5}{9}=\frac{4\cdot 5}{9\cdot 9}=\frac{20}{81}

_____

As written (without parentheses), your expression is evaluated left to right, so evaluates to ...

  4/(9·9·5) = 4/405

Jeremy wants to determine the number of solutions for the equation below without actually solving the equation.
Degger [83]

Answer:

  1 solution

Step-by-step explanation:

Jeremy can simplify the equation enough to determine if the x-coefficient on one side of the equation is the same or different from the x-coefficient on the other side. Here, that simplification is ...

  -3x -3 +3x = -3x +3 +3

We see that the x-coefficient on the left is 0; on the right, it is -3. These values are different, so there is one solution.

__

In the attached, the left-side expression is called y1; the right-side expression is called y2. The two expressions are equal where the lines they represent intersect. That point of intersection is x=3. (For that value of x, both sides of the equation have a value of -3.)

__

<em>Additional comment</em>

If the equation's x-coefficients were the same, we'd have to look at the constants. If they're the same, there are an infinite number of solutions. If they are different, there are no solutions.
