An average-size female spider and a large spider can lay a total of 2100 eggs at one time. the large spider lays 20times the number of eggs as the average-size spider. how many eggs does the average sized spider lay

the average spider lays 100

the large spider lays 2000
together, they lay 2100

To find the number of eggs the average-sized spider lays, let's set up equations based on the information given.

Let's represent the number of eggs laid by the average-sized spider as x.

We know that the large spider lays 20 times the number of eggs as the average-sized spider, which means the number of eggs laid by the large spider is 20x.

According to the given information, the total number of eggs laid by both spiders is 2100. So we can create the equation:

x + 20x = 2100

Combining like terms, we get:

21x = 2100

To solve for x, divide both sides of the equation by 21:

x = 2100 / 21

Simplifying the expression, we get:

x = 100

Therefore, the average-sized spider lays 100 eggs.
