When it's laid out like that. 2 division statements on either side with one unknown variable you just cross multiply really easy
5 x 24 / 6 = 20
Take the number that's on the same position of the x thats 5 then multiply it to the numerator or denominator of the x thats 24 then divide it to its denominator thats 6
Answer:
P43=4!(4–3)!=241=24
Step-by-step explanation:
There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.
This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:
P43=4!(4–3)!=241=24
Answer:
56
Step-by-step explanation:
sum of 3 floors, and you dont know the three floors so well name each x, so
x+x+x=168
3x=168
x=56
so each floor is 56ft
Answer:
Twelve tickets cost $30.00
Step-by-step explanation:
Answer:
x ≈ 1091.63
Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x = 
note that ln x is to the base e
Given
ln(x + 5) = 7, then
x + 5 = 
( subtract 5 from both sides )
x = - 5 ≈ 1091.63 ( nearest hundredth )
