Grouping like terms, 7 x + 7 + 6 x - 9 = (7 x + 6 x) + (7 - 9):

(7 x + 6 x) + (7 - 9)

7 x + 6 x = 13 x:

Answer:  \bold{k=\dfrac{Fr^2}{qQ}}

<u>Step-by-step explanation:</u>

Isolate k by multiplying both sides of the equation by \dfrac{r^2}{qQ}

F=k\dfrac{qQ}{r^2}\\\\\\F\bigg(\dfrac{r^2}{qQ}\bigg)=k\dfrac{qQ}{r^2}\bigg({\dfrac{r^2}{qQ}\bigg)

\large\boxed{\dfrac{Fr^2}{qQ}=k}

Answer:

The experimental probability P(E) is 0.1818 = 18.18%

Step-by-step explanation:

The experimental probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

11 trials(11 outcomes)

2 kings(2 desired)

So

P(E) = 2/11 = 0.1818

The experimental probability P(E) is 0.1818 = 18.18%

HELPPP . One side of a triangle is half the longest side. The third side is 8 meters less than the longest side. The perimeter i
Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

Side A is the longest side

Side B is half of A = A/2

Side C is 8m less than A = A-8

Perimeter of traingle = A+B+C

52 = A + A/2 + A-8

Collect like terms

52+8= A+A/2+A

60 = 5/2 A

Divide 60 by the coefficient of A

60÷5/2 = A

60×2/5= A

A=24m

Substitute the value of A into the expressions for sides B and C

Side B =A/2=24/2=12m

Side C =A-8=24-8=16m

The sides of the triangle are 24m, 12m and 16m
