\frac{8x-2}{x-8} - \frac{2}{x-8}

The fractions already have a common denominator of x-8, so all wee need to do is combine the numerators:

\frac{8x-2-2}{x-8}

\frac{8x-4}{x-8}

Points J, K and L are collinear with J between L and K. If KJ = 2x-3, LJ= 4x-8, solve for x:
notsponge [240]

Your question is incomplete, here is the complete form.

Points J, K and L are collinear with J between L and K.  If KJ = 2x - 3, LK = 9x + 7 and LJ = 4x - 8,  solve for x:

Answer:

The value of x is -6 ⇒ B

Step-by-step explanation:

∵ J, K, and L are collinear

→ That means they form a straight segment

∵ J is between K and L

→ That means J divides LK into two segments KJ and LJ

∴ LK = KJ + LJ

∵ LK = 9x + 7

∵ KJ = 2x - 3

∵ LJ = 4x - 8

→ Substitute them in the equation above

∴ 9x + 7 = (2x - 3) + (4x - 8)

→ Add the like terms in the right side

∵ 9x + 7 = (2x + 4x) + (-3 - 8)

∴ 9x + 7 = 6x + -11

∴ 9x + 7 = 6x - 11

→ Subtract 7 from both sides

∵ 9x + 7 - 7 = 6x - 11 - 7

∴ 9x = 6x - 18

→ Subtract 6x from both sides

∵ 9x - 6x = 6x - 6x - 18

∴ 3x = -18

→ Divide both sides by 3

∵ \frac{3x}{3}=\frac{-18}{3}

∴ x = -6

∴ The value of x is -6

Picking a number that is divisible by 5 from a jar with papers labeled from 1 to 12
kogti [31]
Total number of possible outcomes:12
Number of favourable outcomes:2( since only two numbers divisible by 5 in that range are 5 and 10)
The possibility that you'll pick a number divisible by 5 is 2/12 or 1/6
Hope that's what you're looking for since you didn't specify.
