Answer:

$\frac{-4x+7}{2(x-2)}$

Step-by-step explanation:

$For x \neq 1 \\\frac{\frac{3}{x-1}-4}{2-\frac{2}{x-1}}=\frac{\frac{3}{x-1}-\frac{4x-4}{x-1}}{\frac{2x-2}{x-1}-\frac{2}{x-1}}=\frac{\frac{-4x+7}{x-1}}{\frac{2x-4}{x-1}}=\frac{-4x+7}{2(x-2)}$

2) -2(7n – 6) +n=-3 - 8n

iogann1982 [59]

Answer and Step-by-step explanation:

For this equation the answer is : $n=3$

Step 1 : Simplify both the sides of the equation :

$-2(7n-6)+n=-3-8n$

$(-2)(7n)+(-2)(-6)+n=-3+-8n$ (Distribute)

$-14n+12+n=-3+-8n$

$(-14n+n)+(12)=-8n-3$ (Combine the like terms)

$-13n+12=-8n-3$

Step 2 : Add " $8n$ " to both the sides :

$-13n+12+8n=-8n-3+8n$

$-5n+12=-3$

Step 3 : Subtract " $12$ " from both the sides :

$-5n+12-12=-3-12$

$-5n=-15$

Step 4 : Divide both the sides by " $-5$ "

$\frac{-5n}{-5} =\frac{-15}{-5}$

$n=3$

That's your final answer : $n=3$

Andy flipped a coin once and rolled a six-sided number cube numbered 1 through 6. The list below shows the possible outcomes whe

zhuklara [117]

Answer:

C. 1/4

Step-by-step explanation:

The probability of landing tails is 50%, since coins are two sided.

If a cube has 6 numbers, the probability of getting an even number is also 50% since 2,4,and 6 are even while 1,3, and 5 are odd.

The probability of getting both would be 25% (I multiplied 1/2 by 1/2)

The values of x and y vary directly

ss7ja [257]

Answer:

y = (1/4)x

Step-by-step explanation:

"Direct variation" here signifies y = kx, where k is the constant of proportionality.

Then y = kx. Here we are to find k using the info that x = 12 and y = 3:

3 = k(12), or

k = 3/12, or k = 1/4

Then y = (1/4)x
