Answer:

There is a 1/8 chance.

If there are 4 cards in the deck, and one three card, it makes it a 1/4 chance of picking the card the first time.

The probability stays the second time you pull out a card.

So, you would do the equation 1/4 * 1/4, which is 1/8. That is the answer.

2(4x – 3) ≥ –3(3x) + 5x?

Treat the 'more than or equal to' sign as a '=' then work it out like an ordinary algebraic equation.
2(4x-3) = -3(3x)+5x
8x-6 = -9x+5x
-6 = -9x+5x-8x
-6 = -12x
-6/-12 = x
1/2 = x
Then swap the '=' back for the other sign. This works for all of the '<' type signs

Which expression is equivalent to 4√32⋅√2 ?

bonufazy [111]

$4\sqrt{32}\times\sqrt{2}\rightarrow4\sqrt{32\times2}$ <em>because two square rooted numbers multiplied together equals the square root of the radicands </em>(the number under a square root symbol is the "radicand"

<u>so now you have</u>: $4\sqrt{64}=4\times(\pm8)$
Depending on the choices, you can have either $4\times8=32$ or $4\times(-8)=-32$
