A high school choir had a car wash to raise money. The number of trucks washed was 5 fewer than twice the number of cars washed. If they washed a total of 34 trucks and
cars, how many trucks did they wash?
Please help

They washed 13 trucks.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that

x is the number of trucks washed

y is the number of cars washed.

The number of trucks washed was 5 fewer than twice the number of cars washed.

This means that

They washed a total of 34 trucks and cars

This means that

How many trucks did they wash?

This is y.

Since

They washed 13 trucks.

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 !
