Answer:
Spiders=8
Ants=12
Step-by-step explanation:
Spider(s)=8 legs
Ants(a)=6 legs
Total legs=136
Total heads=20
8s+6a=136 (1)
s+a=20 (2)
From (2)
s=20-a
Substitute 20-a into (1)
8s+6a=136
8(20-a)+6a=136
160-8a+6a=136
160-2a=136
-2a=136-160
-2a=-24
a= -24/-2
a=12
Substitute a=12 into (2)
s+a=20
s+12=20
s=20-12
s=8

We have been given that Khalil has 13.5 M of lanyard. He needs to cut the lanyards into pieces that are 90 cm long. We are asked to find the number of full-length pieces of a lanyard will Khalil be able to cut.
First of all, we will convert 13.5 meter into cm.
1 meter = 100 cm
13.5 meters = 13.5*100 = 1350 cm.
Now we will divide 1350 by 90 to find number of pieces of lanyard that can be cut from 1350 cm.
![\text{Number of full-length pieces of a lanyard}=\frac{1350}{90}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20full-length%20pieces%20of%20a%20lanyard%7D%3D%5Cfrac%7B1350%7D%7B90%7D)
![\text{Number of full-length pieces of a lanyard}=15](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20full-length%20pieces%20of%20a%20lanyard%7D%3D15)
Therefore, Khalil will be able to cut 15 full-length pieces of a lanyard.
