Answer:

<h2>x = 14</h2><h2 />

Step-by-step explanation:

7x + 9 + 5x + 3 = 180

7x + 5x = 180 - 3 - 9

12x = 168

x = 168 / 12

x = 14

Answer:

14

Step-by-step explanation:

By applying the vertical angle theorem to 5x + 3, using same-side exterior angle theorem, we can find that:

(7x + 9) + (5x + 3) = 180

Now to find x, we can just solve for x in the equation we found.

(7x + 9) + (5x + 3) = 180

Combine like terms.

12x + 12 = 180

Subtract 12 from both sides.

12x = 168

Divide both sides by 12.

x = 14

So the value of x would be 14.

I hope you find my answer and explanation to be helpful. Happy studying.

Given that (1, 0, 1) is a solution to a system of three linear equations, which of the following is true about the system?
Anna35 [415]
<h3>Answer:  Choice C) </h3><h3>The system can only be independent and consistent</h3>

===========================================================

Explanation:

Let's go through the answer choices

  • A) This isn't possible. Either a system is consistent or inconsistent. It cannot be both at the same time. The term "inconsistent" literally means "not consistent". It's like saying a cup is empty and full at the same time. We can rule out choice A.
  • B) This is similar to choice A and we cannot have a system be both independent and dependent. Either a system is independent or dependent, but not both. Independence means that the two equations are not tied together, while dependent equations are some multiple of each other. We can rule out choice B.
  • C) We'll get back to this later
  • D) The independence/dependence status is unknown without the actual equations present. However, we know 100% that this system is not inconsistent. This is because the system has at least one solution. Inconsistent systems do not have any solutions at all (eg: parallel lines that never cross). We can rule out choice D because of this.

Going back to choice C, again we don't have enough info to determine if the system is independent or dependent, but we at least know it's consistent. Consistent systems have one or more solutions. So part of choice C can be confirmed. It being the only thing left means that it has to be the final answer.

If it were me as the teacher, I'd cross out the "independent" part of choice C and simply say the system is consistent.
