A. multiply all the numbers together to find the possible outcomes
4 x 4 = 16
There are 16 different jacket-shirt outfits Ardell have.
They will not be the same color = 4 x 3
4 x 3 = 12
12/16 = 0.75, or a 75% chance they will not be the same color
hope this helps
For example 1ft = 12in so 12 is the number that you are going to multiply so just multiply 25×12 and that is your answer
3x + (-2x) would be just subtracting 2x from 3x, so it would be 1x or x. Hope this helped<3
Set the whole expression = to 0 and solve for x.
3x^(5/3) - 4x^(7/3) = 0. Factor out x^(5/3): x^(5/3) [3 - 4x^(2/3)] = 0
Then either x^(5/3) = 0, or 3 - 4x^(2/3) = 0.
In the latter case, 4x^(2/3) = 3.
To solve this: mult. both sides by x^(-2/3). Then we have
4x^(2/3)x^(-2/3) = 3x^(-2/3), or 4 = 3x^(-2/3). It'd be easier to work with this if we rewrote it as
4 3
--- = --------------------
1 x^(+2/3)
Then
4
--- = x^(-2/3). Then, x^(2/3) = (3/4), and x = (3/4)^(3/2). According to my 3 calculator, that comes out to x = 0.65 (approx.)
Check this result! subst. 0.65 for x in the given equation. Is the equation then true?
My method here was a bit roundabout, and longer than it should have been. Can you think of a more elegant (and shorter) solution?
