Solve for K 7K-6 2K+14

Mathematics
1 answer:
Verdich [7]2 years ago
8 0

Answer:

k=4

Step-by-step explanation:

Using the diagram, we can conclude that the given angles are vertical angles. Vertical angles are opposite angles that are formed when two lines intersect. Vertical angles are always congruent.

Using this information we can set up an equation.

7k-6=2k+14

Subtract 2k from both sides.

7k-2k-6=2k-2k+14\\5k-6=14

Add 6 to both sides

5k-6+6=14+6\\5k=20

Divide both sides by 5

\frac{5k}{5}=\frac{20}{5}\\k=4

CHECK:

7(4) - 6 = 28 - 6 = 22

2(4) + 14 = 8 + 14 = 22

22 = 22

Cross-multiplication is helpful in: a. quadratic equations c. linear equations b. solving proportions d. word problems
Romashka [77]

Answer:

Cross multiplying fractions helps us to see if numbers are equal, and if not, which is bigger and which is smaller. But that is not its only use. Cross multiplying fractions can help us to solve for unknown variables in fractions.

1.The height and radius are the same in both cylinders. Which cylinder has the greatest volume?
natulia [17]
Problem One
This is one of those questions that you might think is silly until you try it for yourself or you read about it.

The thing you have to understand, which is not well stated, is that oblique cylinders have circles on the top and bottom. You guys (in the United States) still have pennies, don't you? Take 10 or twelve of them and  make a stack where each penny sticks out 1/16 of an inch from the edge of the penny below it. I can't draw it I don't think (even my stick men look like someone who can't hold a pencil drew them), but maybe I can find a picture or you can. 


Got it. 

So the oblique cylinder has a circle on the top and bottom, just the way the pennies do when you stack them like the cylinder below. Then you can stack them like a soup can. Did anything change? No

The correct answer is (drum roll please) <<<<<<< <em>They are the same volume.


</em>Problem 2
<em />Suppose you have a glass whose sides are straight up and down (a right cylinder with no top). You fill the glass with water. Stop a moment to consider this. Now magically  you place a plain right through the middle of the glass. 

Question: is there any difference between the shape of the plain at the top of the glass than that shape at the middle? (You should answer that they are the same shape -- a circle --  at both the top and middle of the glass).

If you caught on, you would have said that the shapes are the same in your question.

3/4x + 2 = 3/8x - 4<br> X=<br> Please show how u got ur answer
ch4aika [34]

Answer:

Hope it helps u

Step-by-step explanation:

3/4x + 2 = 3/8x - 4

subtract 2 from both sides we get

(3/4)x=(3/8)x-6

subtract (3/8)x from both sides, we get

(3/4)x-(3/8)x= -6

now taking L.C.M we get

((6-3)/8)x= -6

(3/8)x= -6

x= -6*8/3

<h2>x= -16</h2>

Answer plsssss………………
vova2212 [387]

Answer:

The corresponding angles theorem works for cases where we have two parallel lines intersecting another line.

Two lines are parallel if, at any point, the distance between these two lines is always the same.

Now, if we look at the image, we can see that the distance between the two horizontal lines changes (is smaller at the right and larger at the left)

Thus, these lines are not parallel.

Then the corresponding angles theorem can not be used here, and we have that:

∠9 ≠ ∠10
