When jose took the test over, he increased his score by 15 percentage points. jose raised his score to an 83% on the test. which of the following equations represents the word problem if "x" represents jose's score on the first test? x + 15 = 83 x = 15 + 83 x - 15 = 83

The correct equation is  x+15=83

Option 1 is correct.

Step-by-step explanation:

When Jose took the test over, he increased his score by 15% points

Let he scored in first test x%

In second test scored 83% which was 15% more than first test.

He increased his score by 15% points from first test.

Thus, Scored in second test = x + 15

We are given second test scored 83%

Therefore, x+15 must be equal to 83

Hence, The correct equation is  x+15=83

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
