How do I even write an equation for this problem all i need someone to show me how to get an equation so i can solve it.
It is estimated that the Earth is losing 4000 species of plants and animals every year. If S represents the number of species living last year, how many species are on Earth this year?
S-4000.
oh thank you i wasn't sure that's what i was thinking but i was dobting it.
t is estimated that the earth is losing 4000 species of plant and animals every year if s represents the number of species living last year how many species are on eath this year
To write an equation for this problem, we can represent the number of species living this year as a variable. Let's call it X.
According to the problem, it is estimated that the Earth is losing 4000 species of plants and animals every year. So, if S represents the number of species living last year, we can represent the number of species this year as:
X = S - 4000
Here, S is the number of species living last year, and X is the number of species living this year. By subtracting 4000 from S, we account for the estimated loss of species.
To find the number of species on Earth this year, you just need to substitute the value of S into the equation.
