Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:
That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.
For example,

Answer:
Option D: 10.7 is the correct answer.
Step-by-step explanation:
Given that:
Hypotenuse of right triangle = 14
Height of right triangle = 9
Length of missing side = b
We can solve for missing side length by using Pythagorean theorem;
Here,
a = 9 , c = 14
Subtracting 81 from both sides
Taking square root on both sides
The length of missing side is 10.7
Hence,
Option D: 10.7 is the correct answer.

Step-by-step explanation:
Humans have made use of natural numbers as long as humans have been around. Counting numbers are wired into our consciousness, as they are for many living things.
Research has demonstrated some plants can count up to 5 (generally, carnivorous ones). Honeybees have long been known to be able to count to 4, and recent research shows they can count higher. Fish can count; birds can count; as can many other species.
For most, it takes concentration and/or training to count beyond 4. We are born with an understanding of 1, 2, 3, more.
Nobody "invented" natural numbers.

<em>Additional comment</em>
Prey species survive by being able to count predators. Some predators take advantage of the limitations of number recognition by hunting in groups larger than can be readily counted.
