Nancy and kevin collect coins. nancy has x coins. kevin has 4 coins fewer than two times the number of coins nancy has. write and simplify an expression for the total number of coins nancy and kevin have.

total: 3x + 4

Step-by-step explanation:

Nancy = x

Kevin = 2x+4

together = 3x + 4

The expression for the total number of coins owned by both Nancy and Kelvin is

= x + 2x - 4

= 3x - 4

Step-by-step explanation:

The relationship between the number of coins collected by each person is given in the statement "Nancy has x coins. Kevin has 4 coins fewer than two times the number of coins Nancy has."

Number of Nancy's coins = x

Since Kevin has 4 coins fewer than two times the number of coins Nancy has

Number of Kelvin's coins = 2x - 4 = 2(x-2)

Hence the expression for the total number of coins Nancy and Kelvin have

=x + 2x - 4

= 3x - 4

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 !
