The rule associated with moving decimal places, and multiplying by a value or multiple of 10, would be the following :
If you divide a value by 10 or a multiple of 10, you would move the decimal place to the left number of times as there are zeros in the multiple.
(Assuming that there are no zeros in the numerator value)
If you multiply by 10 multiple, then you would move the decimal to the right that many times as there are 0's in the value.
The solution would be that the decimal number is multiplied by 100.
A) if 3.5 fudge is 18.20 then 3.5 times 2 is 7 then 18.20 times 2 is 36.40 which is how much it will cost.
B) i believe it would be 5.20x because it’s always changing at that rate
I = Prt
To find out what r is, you'll need to move P and t to the other side.
To get rid of multiplication, you divide.
I/Pt= Prt/Pt
Answer: I/Pt= r

Answer:
Step-by-step explanation:
Since you know x is between 4 and 5, lets start in the middle using 4.5 for x
4.5^3 - 5(4.5) = 68.625 ( this is larger than 59, so we know the number is less than 4.5)
lets try 4.2: 4.2^3 -5(4.2) = 53.088 ( this is smaller than 59, so we know the number is larger than 4.2)
4.3: 4.3^3 -5(4.3) = 58.007
4.4: 4.4^4 -5(4.4) = 63.184
so we know the answer is between 4.3 and 4.4
4.32: 4.32^3 - 5(4.32) = 59.02 round to 59.0 ( to 1 decimal place)
I think this is what the teacher wants for an answer.
