Answer:

Step-by-step explanation:

P=2a+b

Solve for a.

Divide both sides by 2 to isolate a.

P=2a+b

P/2=a+b/2

When you rewrite the equation, it becomes:

a=P/2-b/2 (The sign changes from a positive to a negative because you need to move P/2 to the other side to get a to one side)

Therefore, your final answer is: a=P/2-b/2

Hope this helped!

Find the value of w-9 given that –3w+5 = 2

melamori03 [73]

Answer:

$-8$

Step-by-step explanation:

Solving for $w$ given the equation, $-3w +5 = 2$ :

$-3w +5 = 2 \\ -3w +5 -5 = 2 -5 \\ -3w = -3 \\ \frac{-3w}{-3} = \frac{-3}{-3} \\ w = 1$

Solving for $w -9$ when $w = 1$

$1 -9 \\ -8$

Answer:

$\approx 0.482659$

Step-by-step explanation:

The experimental probability is the chance of an event happening based on data, or rather the experiment results, and not on a theoretical calculation. In essence, a theoretical calculation can be described by the following formula:

$\frac{desired}{total}$

However, the experimental probability can be described with the following formula:

$\frac{number\ of\ desired\ outcomes}{number\ of \ trials}$

The number of trials is the sum of the number of outcomes. In this case, the desired outcome is tails. Therefore, the experimental probability can be described using the following formula:

$\frac{tails}{total}$
