Answer:

Part 1) see the procedure

Part 2) $4.95x+49.95 < 9.95 x$

Part 3) $x > 9.99\ months$

Part 4) The minimum number of months, that he needs to keep the website for site A to be less expensive than site B is 10 months

Step-by-step explanation:

Part 1) Define a variable for the situation.

Let

x ------> the number of months

y ----> the total cost monthly for website hosting

Part 2) Write an inequality that represents the situation.

we know that

Site A

$y=4.95x+49.95$

Site B

$y=9.95x$

The inequality that represent this situation is

$4.95x+49.95 < 9.95 x$

Part 3) Solve the inequality to find out how many months he needs to keep the website for Site A to be less expensive than Site B

$4.95x+49.95 < 9.95 x$

Subtract 4.95x both sides

$4.95x+49.95-4.95x < 9.95 x-4.95x$

$49.95 < 5x$

Divide by 5 both sides

$49.95/5 < 5x/5$

$9.99 < x$

Rewrite

$x > 9.99\ months$

Part 4) describe how many months he needs to keep the website for Site A to be less expensive than Site B.

The minimum number of months, that he needs to keep the website for site A to be less expensive than site B is 10 months

Given:

The equation is

$\dfrac{1}{3}x=\dfrac{1}{5}$

To find:

The coefficient and reciprocal.

Solution:

We have,

$\dfrac{1}{3}x=\dfrac{1}{5}$

Here, $\dfrac{1}{3}$ is multiplied with x.

So, the coefficient of x is $\dfrac{1}{3}$ .

To find the reciprocal, we need to interchange numerator and denominator of a fraction.

So, the reciprocal of $\dfrac{1}{3}$ is $\dfrac{3}{1}=3$

Therefore, the reciprocal is 3.

5+k-5k=-4k+6 solve for k

marissa [1.9K]

Hey there

the answer is

5+k−5k=−4k+6

5+k+−5k=−4k+6

(k+−5k)+(5)=−4k+6

−4k+5=−4k+6

−4k+5+4k=−4k+6+4k

5=6

5−5=6−5

0=1

thank you

best regards

Answer:

Step-by-step explanation:

Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.

To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.

Keep in mind that these points are only roughly placed on the map.

But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.

To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.

47 - 35 = 12

To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.

122 - 78 = 44

I assume that the answer you should pick is D. (12, 44)

However, that doesn't exactly answer the question... it's worded a little weirdly.

To solve the rest of the equation, do the following:

Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.

a^2 + b^2 = c^2

12^2 + 44^2 = c^2

144 + 1936 = c^2

2080 = c^2

c = $\sqrt{2080}$

c = 45.61

The answer is 45.61 units.
