Angle JKL is 54 degrees. What is the measure of angle MKL? *
hoa [83]

Answer:

MKL = 36°

Step-by-step explanation:

(3x + 6) + (6x + 12) = 54°

3x + 6x + 6 + 12 = 54

9x + 18 = 54

9x = 54 - 18

9x = 36

x = 36/9

x = 4

MKL = 6x + 12

MKL = 6(4) + 12

MKL = 24 + 12

MKL = 36°

4x+8y=17<br> Solve for y
olasank [31]

Answer:

4x + 8y = 17  

Solve for y.

You want to get y on one side of the equal sign by itself so... you subtract 4x from both sides to get:

8y = -4x + 17

Then you divide both sides by 8 to get:

y= -4x/8 +17/8

Then simplify the fractions to get:

y = -2x/4 + 17/8
