JK = 7x + 9<br> JL = 114, and<br> KL = 9x + 9,<br> Find KL.
VikaD [51]

Answer:

KL= 63

Step-by-step explanation:

JK=7x+9 , JL=114 , KL=9x+9 ( if the points are on the same line and point J at the end point and K in the middle)

*J_______________________K___________________________L

JL=JK+KL

114=7x+9+9x+9

114-18=16 x

16x=98

x=98/16=6

KL= 9x+9

KL=9(6)+9

KL= 63

Solve the equation 2x+3/3 - 3x/2=-4<br>Fast please
alina1380 [7]

Answer:

x = 6

Step-by-step explanation:

Assuming the equation is

\frac{2x+3}{3} - \frac{3x}{2} = - 4

Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions

2(2x + 3) - 9x = - 24

4x + 6 - 9x = - 24

- 5x + 6 = - 24 ( subtract 6 from both sides )

- 5x = - 30 ( divide both sides by - 5 )

x = 6
