Answer:
2.21073919x10^23
Step-by-step explanation:
Apply the Negative Exponent Rule. Negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.
Answer:
The answer should be .25
Step-by-step explanation:
The answer should be .25 because:
- there are 4 places you can score and since you want it to land on 5 and there is only one 5 it counts as a 1
- the since there are 4 in total and you want to land on 1 you get 1/4 the number one standing for there only being one 5 and the 4 standing for the number of places to land on.
-then you convert the 1/4 into a decimal which makes .25
Part A:
-np - 70 < 40
+70
-np < 110
-n < 110/p
Part B
4w-7k=28
-7k=28-4w
7k=4w-28
k=4/7w-4
The scenario will will be represented by: 
The number will be -13
Step-by-step explanation:
We have to convert the given situation into the mathematical form
Let x be the number
Then
"a number plus itself"
x+x
"plus twice itself"
x+x+2x
"plus 4 times itself"
x+x+2x+4x
"is equal to -104"

Hey!!
here is your answer >>>
the total money is 270 , it is shared among three people .
let's take the amount of Polly as X
then, the amount of Andy would be 2x
then, the amount of Phoebe would be 6x
the sum of 6x,2x and x is 270!.
let's add them up,
9x = 270
x = 30!.
Polly = £30
Andy= £60
Phoebe = £180
Hope my answer helps!
