Answer:
(9-6.6)÷2=x
Step-by-step explanation:
Do it in reverse from 9 all the way to x.
Distribute
remember a(b+c)=ab+ac
we can actually divide both sides by x
5(4x+8)=4(6x-10)
distribute
20x+40=24x-40
minus 20x both sides
40=4x-40
add 40 both sides
80=4x
divide by 4
20=x
Answer:
Step-by-step explanation:
Given that an ice cream shop has 25 different flavors of ice cream.
a) the number of different 3-scoop ice cream cones that are possible if all three scoops are different
=25P3 (since order matters as shapes or colours would be different so different order will give different type)
= 13800
b) the number of different 3-scoop ice cream cones that are possible if all three scoops are different
=25C3 (since order does not matter here)
=2300
c) the number of different ice cream cones if all three scoops could be the same, and the order of the
flavors is important
= when all three sceeps couldbe the same we can say that these are with replacement. Neither permutation nor combination
Each scoop can be any one of the 25
no of ways
