8 ÷ (2/3)
Divide 2/3 first, because it's in the parenthesis.
Divide 8 by the product of 2/3 = 12.
Let, number of spiders = x
number of insects = y
6x + 8y = 36
remember, legs can't be in fraction or decimal.
So, only (3, 2) fits with that.
So, there are 3 spiders & 2 insects in his collection.
Hope this helps!

Answer:
5 or 6
Step-by-step explanation:
So I did it in a different way than shown in rsm classes. I said that the speed was x-2 and x.
then I said the distance was 6 and 15. If the time taken was 1 hour more, then we can come up with this equation:
Since the time is 6/x-2 or 15/x
15/x-6/x-2=1
multiply everything to get a common denominator then cancel it out to get
(15x-30)-6x=x^2-2x
11x-30=x^2
x^2-11x+30=0
(x-5)(x-6) is factored form.
so x=5 or x=6. this means that the speed of the boat is either 5km/h or 6 km/h
