Hi,

2k -- 4 = 2k -- 2·2 = 2·(k -- 2).

If you divide this by k -- 2, you get 2.

Answer: 2

Step-by-step explanation:

2k-4 is equivalent to k-2 times 2 (distributive property)

If you divide it by that number, the remainder is 2.

If cos theta=-2/3, which of the following are possible (Help asap)

alexgriva [62]

Answer:

The correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$

Step-by-step explanation:

given $cos\theta=-\frac{2}{3}$

Since, $cos\theta=\frac{base}{hypoteneous}$

it means prependicular of right angled triangle can be calculated by pythagoras theorem as:

base² + prependicular² = hypoteneous²

2² + prependicular² = 3²

4 + prependicular² = 9

prependicular² = 9 - 4

prependicular² = 5

prependicular = √5

Since, $sin\theta=\frac{prependicular}{hypoteneous}$

$sin\theta=\frac{\sqrt{5}}{3}$

Since, $tan\theta=\frac{prependicular}{base}$

$tan\theta=\frac{\sqrt{5}}{2}$

Hence, the correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$

3k-5=20k solve the following equation for k

Virty [35]

Answer:

K = 8.3 repeating or 8 1/3

Step-by-step explanation:

3k - 5 = 20

Add 5 to the '-5' and 20 so you'll now have 3k = 25 (You're isolating the variable )

3k/3 = k

25/3 = 8.3 repeating or 8 1/3

K = 8 1/3 or 8.3 repeating.

What is the value of x?

Westkost [7]

Answer:

x is equal to 20 in this picture.

Step-by-step explanation:

In order to find this, we need to note that these two angles will be equal to each other. Now we can put their values equal to each other and solve for x.

3x + 50 = 6x - 10

50 = 3x - 10

60 = 3x

20 = x
