Answer:

25. Hope this helps :)

Step-by-step explanation:

180-70=110

110-55=55

55-30=25

Your missing answer would be 25

Answer:

x=25

Step-by-step explanation:

First, we add all like terms. Then, we solve for x.

70+x + 55 + 30 = 180\\x+70 + 55 + 30 = 180\\x+155=180\\x=25

We can rearrange some things because order does not matter with addition. Next, we just use basic equation solving techniques.

With unique examples of your own let’s discuss the number of solutions possible (0, 1, 2, 3, 4) to a system of equations that in
chubhunter [2.5K]

The number of solutions possible to a system of equations that include a conic section depends on the type of equations involved

<h3>How to determine the number of solutions?</h3>

A system of equation that has a conic section may or may not have solutions.

It would have a solution if the equations intersect, when plotted on a graph and it would not, if otherwise

A conic section can be any of:

  • Parabola
  • Ellipse
  • Hyperbola
  • Circle

<u>Example 1: No solution</u>

Consider the following system of equations

  • y = x² - 10 --- parabola equation
  • (x - 1)² + (y - 2)² = 5 --- circle

The above system of equations has no solution because they do not intersect when plotted on a graph (see graph 1)

<u>Example 2: One solution</u>

Consider the following system of equations

  • x = 2 --- linear equation
  • y = x² - 10 --- parabola

The above system of equations has one solution because they intersect at one point (see graph 2)

<u>Example 3: One solution</u>

Consider the following system of equations

  • y = 2x + 1 --- linear equation
  • y = x² - 10 --- circle

The above system of equations has two solutions because they intersect at two points (see graph 3)

The above examples imply that a system of equations that involves conic section can have as many solutions as possible.

The number of solutions depends on the type of equations involved

The attached graphs illustrate how a system of equations can have 0 to 4 solutions
