0.5 is the answer to that I hope I got it right

Solve. -2(6 - 20n) = 20(2n - 3)a. 40
b. 36
c. no solution
d. all real numbers

Answers

The equation -2(6 - 20n) = 20(2n - 3) has no solution.

Hence the correct option is C.

Given is an equation -2(6 - 20n) = 20(2n - 3), we need to solve it for n,

Let's solve the equation step by step:

-2(6 - 20n) = 20(2n - 3)

First, distribute the -2 on the left side and the 20 on the right side:

-12 + 40n = 40n - 60

Next, let's move all the terms with "n" to one side of the equation:

-12 + 40n - 40n = 40n - 40n - 60

-12 = -60

Now, we can see that the equation is inconsistent, as there are no values of "n" that satisfy this equation.

Therefore, the correct answer is:

c. no solution

-2(6-20n) = 20(2n-3)
-12 + 40n = 40n - 60
40n = 40n - 60 + 12
40n - 40n = 60 + 12       (dont minus 40n - 40n yet, we can factorise it)
n(40-40) = 60 + 12
n = (60 + 12)/(40-40) 
n = 60 + 12/ 0

Therefore no solution as we cannot divide by 0

Consider the following food chain: Plants are eaten by grasshoppers, which are eaten by mice, which are eaten by snakes. What would happen to the other members of the food chain if the plant population was wiped out?
a. The populations of grasshoppers, mice, and snakes would increase.
b. The populations of grasshoppers and mice would increase, while the population of snakes would decrease.
c. The populations of grasshoppers would decrease, while the population of mice and snakes would increase.
d. the number of plants will increase, the number of grasshoppers will increase, the number of snakes will increase

Answers

Answer;

-The populations of grasshoppers, mice, and snakes would decrease.

Explanation;

-The food web or a food chain describes the series of relationships that occur between predators and prey in an ecosystem.

-Several types of life forms form the food web. Green plants that can make their own food through photosynthesis are the web's producers. They form the bottom of the chain. Animals that get food from other animals and plants are consumers. Decomposers feed off dead plants and animals because decomposers cannot make their own food.

-If producers were removed in a food chain then, all the other animals in the food web would die too, because their food supplies would have died out. The populations of the consumers would fall as the population of the producer fell.
