In aunt melly’s attics there are also spiders and ants, the total of 136 legs and 20 heads. if a spider has 8 legs and an ant has 6 legs, how many spiders and how many ants are there?in 5 min to 10 min

I would say Aunt Melly needs an exterminator...lol

there are 20 heads...so u know there r gonna be 20 insects total
spiders (s) have 8 legs and ants (a) have 6 legs

s + a = 20 headss = 20 - a
8s + 6a = 136 legs

8(20 - a) + 6a = 136
160 - 8a + 6a = 136
-8a + 6a = 136 - 160
-2a = -24
a = -24/-2
a = 12

s + a = 20
s + 12 = 20
s = 20 - 12
s = 8

so there r 8 spiders and 12 ants

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

What's the denominator
