Answer:
7*(x-4)=-10
Step-by-step explanation:
We have 3 white balls in the first urn out of 9. That means we have a 1 in 3 chance at picking the white ball in the first urn.
Now, we have a 3 in 11 chance at picking the white ball in the second urn.
Since, we want them simultaneously, we need to multiply them.
1/3 × 3/11 = 1/11 chance
Answer:
x^-5 = x to the power of negative 5
Step-by-step explanation:
Which of these is equivalent to 1 over x to the power of 5 ?
Mathematically this is expressed as
(1/x)⁵
We have a rule when it comes to expressing power
(1/a)^b = a^-b
Hence, applying this rule to our question
(1/x)⁵ = (1/x)^5
= x^-5
This is written in words as:
x to the power of negative 5
Each pretzel is 4.5 $
1.50 • 5 = 7.5
7.5 - 30 = 22.5
22.5 / 5 = 4.5
so in conclusion, those are some expensive a** pretzels.
6x = 15
I apologize if this is wrong!
