an averaga-sided female spider and a large spider can lay a total of 2100 eggs at one time. the large spider lays 20 times the number of eggs as the average sized spider. how many eggs does the average side spider lay?

  • 3rd grade math 1 - ,

    As+Ls=2100
    Ls=large spider as=average sized spider

    Ls=20As
    so
    as+20as=2100
    21as=2100
    as=100

    The average sized spider lays 100 eggs at one time

    let the no. of eggs laid by average side spider=x
    given, 20x= 2100
    divide both sides by 20
    20x/20 = 2100/20
    x =105
    . .
    . the no. of eggs laid by an average side spider = 105 eggs
