For this case we must solve each of the equations proposed:
A) 
We apply distributive property to the terms within parentheses:
Subtracting 6 from both sides of the equation we have:
Dividing between -12 on both sides of the equation:
B) 
We apply distributive property to the terms within parentheses:
We add 5m on both sides of the equation:
Dividing between 2 on both sides of the equation:
C) 
We apply distributive property to the terms within parentheses:
We subtract 14 from both sides of the equation:
Dividing between -7 on both sides of the equation:
D) -
We apply distributive property to the terms within parentheses:
We add 28 to both sides of the equation:
Dividing between -21 on both sides of the equation:
Answer:
Answer:are there choises?
Step-by-step explanation:
Volume is 4/3(3.14)(r)^2
the radius is 5.2 ft
Well I don't know.
Let's think about it:
-- There are 6 possibilities for each role.
So 36 possibilities for 2 rolls.
Doesn't take us anywhere.
New direction:
-- If the first roll is odd, then you need another odd on the second one.
-- If the first roll is even, then you need another even on the second one.
This may be the key, right here !
-- The die has 3 odds and 3 evens.
-- Probability of an odd followed by another odd = (1/2) x (1/2) = 1/4
-- Probability of an even followed by another even = (1/2) x (1/2) = 1/4
I'm sure this is it. I'm a little shaky on how to combine those 2 probs.
Ah hah !
Try this:
Probability of either 1 sequence or the other one is (1/4) + (1/4) = 1/2 .
That means ... Regardless of what the first roll is, the probability of
the second roll matching it in oddness or evenness is 1/2 .
So the probability of 2 rolls that sum to an even number is 1/2 = 50% .
Is this reasonable, or sleazy ?
