Answer:

x=13

Step-by-step explanation:

21=8+x

Swap sides so that all variable terms are on the left hand side.

8+x=21

Subtract 8 from both sides.

x=21−8

Subtract 8 from 21 to get 13.

x=13

If (9k, 7k) and (6k, 5k) are two points the graph if a line and k is not equal to 0 what is the sople of the line
olga_2 [115]

Answer:

The answer is 2/3

Step-by-step explanation:

In order to find the slope, we need to use the slope formula.

m (slope) = (y1 - y2)/(x1 - x2)

Now we can plug the points into the equation and solve.

m (slope) = (y1 - y2)/(x1 - x2)

m (slope) = (7k - 5k)/(9k - 6k)

m (slope) = 2k/3k

m (slope) = 2/3

Help will give braniest answer to person who is correct find the degree measure of each angle in the triangle
Irina-Kira [14]

Answer:

Angle I = 90 degrees

Angle J = 61 degrees

Angle K = 29 degrees

Step-by-step explanation:

Angle I is given

We know that the angles in all triangles add up to 180. Since we are given that angle I is equal to 90 degrees, we now know that angle J + angle K = 90 degrees:

(5x+26) + (2x+15) = 90

Solve for X:

7x + 41 = 90

7x = 49

x = 7

Angle J =  (5x + 26) = (5(7) + 26) = 61

Angle K = (2x + 15) = (2(7) + 15) = 29

Checking your work: 61 + 29 = 90
