Answer:

y = (6/11)x + 13/11

Step-by-step explanation:

y = mx + c

m = (-1-5)/(-4-7) = -6/-11 = 6/11

y = (6/11)x + c

When x = 7, y = 5

5 = (6/11)(7) + c

5 = 42/11 + c

c = 5 - 42/11

c = 13/11

y = (6/11)x + 13/11

11y = 6x + 13

Please help me !!! i will mark brain-list for the correct answer !!!

Shtirlitz [24]

Answer:

Step-by-step explanation:

So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.

Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.

Heres what we know however:

angle 1 + angle 2 = 180 degrees.

How do we know this?

Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.

Lets input that into our nice lil equation to get an answer:

7 degrees+angle 2 = 180 degrees

Now lets solve.

Subtract 7 on both sides, and your left with:

angle 2 = 173 degrees.

So the answer must be:

173 degrees

Hope this helps! ;)

Lola's age is 14 more than 6 times Juan's age. The sum of their ages is 35. How old is each?

earnstyle [38]

35 - 14 = 21

3 * 6 = 18

3.5 * 6 = 21

Thus Juan is around the age of 3.5 and Lola is 31.5 I believe

Im not quite sure however I think this is the answer, I hope it helps ^-^

For every 9 black and white copies printed there are 2 color copies printed. If there are 200 color copies printed how many blac

Answer:

900 black and white copies are printed.

Step-by-step explanation:

Given:

For every 9 black and white copies printed there are 2 color copies printed.

If there are 200 color copies printed.

Now, to find the number of black and white copies are printed.

Let the number of black and white copies printed be $x.$

As given, for every 9 black and white copies printed there are 2 color copies printed.

So, 9 is equivalent to 2.

If there are 200 color copies printed.

Thus, $x$ is equivalent to 200.

Now, to solve by using cross multiplication method:

$\frac{9}{2} =\frac{x}{200}$

By cross multiplying we get:

$1800=2x$

Dividing both sides by 2 we get:

$900=x$

$x=900.$

Therefore, 900 black and white copies are printed.
