Answer:
x =
Step-by-step explanation:
First, add like terms. You can take out the x if it's too confusing and add it again.
-5/8 - 7/24 + 1/3 (multiply get a common denominator--in this case it's 24)
-15/24 - 7/24 + 8/24
-14/24 (then, simplify!)
-7/12
(add back the x → -7/12x)
-7/12x = -56 (multiply by reciprocal)
(-12/7) (-7/12x) = (-56) (-12/7)
x = 96
Answer:
It's all about the brackets.
Step-by-step explanation:
If we do (-4)^2, the brackets make it -4 x -4 and the two negatives make a positive of 16.
If we do -4^2, that means that the 4 is squared before putting the minus sign there so you have 4x4 = 16 then put the minus to get -16.
Hope this helps!

Answer:
And replacing we got:
Step-by-step explanation:
We can define the random variable X as the thickness of a protective coating applied to a conductor designed to work in corrosive conditions. And the distribution for X is given by:
And we want to find this probability:
And in order to find this probability we can use the cumulative distribution function given by:
And if we use this formula for the probability desired we have:
And replacing we got:
Answer:
x= -5
Step-by-step explanation:
-3x + 25 = 40
you want to put x terms on one side, numbers on another side
subtract 25 on both sides
-3x = 15
divide both sides by -3
x= -5
