<h3><em>Answer</em><em>:</em></h3><h2><em>3</em><em>2</em></h2>

<em>Solution</em><em>,</em>

<em>2</em><em>x</em><em>-</em><em>5</em><em>6</em><em>=</em><em>8</em>

<em>or,</em><em>2</em><em>x</em><em>=</em><em>8</em><em>+</em><em>5</em><em>6</em>

<em>or,</em><em>2</em><em>x</em><em>=</em><em>6</em><em>4</em>

<em>or,</em><em>X=</em><em>6</em><em>4</em><em>/</em><em>2</em>

<em>X=</em><em>3</em><em>2</em>

<em>Hope </em><em>it</em><em> helps</em>

Answer:

x=32

Step-by-step explanation:

First I put the 56 on the other side by doing the opposite to it, so adding 56 to both sides.

2x - 56 = 8

   +56      +56

2x=64

Then divide both sides by two to single out the x and know it's value

2x=64

/2     /2

x=32

Answer:

Angle STR = 78°

Step-by-step explanation:

So, since line QS is a straight line, we know that it's 180°. We also know that angles QTR and STR both add up to 180°. That gives us an equation:

20x + 12 + 10x + 33 = 180

Combine like terms

30x + 45 = 180

Subtract 45 from both sides

30x = 135

Divide both sides by 30

x = 4.5

Now we know the value of x. We just need to plug it into angle STR's given value:

10(4.5) + 33 = angle STR

45 + 33 = angle STR

78° = angle STR

If a function is derivable at a point it is also continous at that point explain why?
Artyom0805 [142]
For a function to have a derivative in a point has to be continuous at the point, that is, it has to be defined at that point, other wise the derivative would be meaningless.

If there are 19 questions and each question has 4 answers, what is the probability she will answer at least one question correct
gregori [183]

Answer:

0.9958

Step-by-step explanation:

P(being correct) = 1/4 = 0.25

Hence, p = 0.25

n = 19

P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

However, to save computation time, we could use a calculator :

Using a calculator,

P(x ≥ 1) = 0.99577

P(x ≥ 1) = 0.9958

A snake slithers 2/9 miles in 4/5 hours what is its speed in miles per hour
Mamont248 [21]

Answer:

5/18

Step-by-step explanation:

speed = distance / time

s = (2/9 miles) / (4/5 hours)

To divide by a fraction, multiply by the reciprocal:

s = (2/9) × (5/4)

s = 10/36

s = 5/18

So the snake's speed is 5/18 miles per hour.
