<h3>Answer:  1/8</h3>

Explanation:

The only way to get a difference of 2 is to draw a "3" and then a "5" in either order.

The probability of selecting any tile is 1/4. The probability of selecting two particular tiles in a row is (1/4)*(1/4) = 1/16 since we replaced the first tile selected.

2*(1/16) = 1/8 represents the probability of selecting a 3 and 5 in either order.

Help me solve this problem
eduard

Answer:

b.   (-1, 5)

Step-by-step explanation:

Since the first equation is already solved for y, we can use substitution.

Substitute y in the second equation with 3x + 8.

5x + 2y = 5

5x + 2(3x + 8) = 5

5x + 6x + 16 = 5

11x = -11

x = -11/11

x = -1

Now substitute x in the first original equation by -1 and solve for y.

y = 3x + 8

y = 3(-1) + 8

y = -3 + 8

y = 5

Answer: (-1, 5)

Answer:

Option B.

Step-by-step explanation:

The given expression is

\dfrac{10x^2-32}{4}

We need to find the simplified form of given expression.

Taking out GCF from the numerator.

\dfrac{2(5x^2-16)}{4}

Cancel out common factors.

\dfrac{5x^2-16}{2}

The expression \dfrac{5x^2-16}{2} is the simplified form of given expression.

Therefore, the correct option is B.
