Use first differences. You are subtracting. Difference = Subtracting.

9 - x = 4
4 - x = -1
-1 - x = -6

Find for x.

9 - x = 4
   - x = 5
     x = -5

Therefore the answer is B.

Proof:

9 - 5 = 4
4 - 5 = -1
-1 - 5 = -6

The diameter of this beach ball is 12 inches.
Wittaler [7]

Answer:

288π or 904.78

Step-by-step explanation:

We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is \frac{4}{3} × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.

Volume = \frac{4}{3} × π × r³

→ Let's substitute in the values

Volume = \frac{4}{3} × π × 6³

→ Simplify

Volume = \frac{4}{3} × π × 216

→ Simplify further

Volume = 288π or 904.78

Question 1 (3 points) What value of p makes this equation true? 3p - 8 = -23 . O p = -6 Op = -5 Op = 5 p = 6​
olchik [2.2K]

The value of p that makes the given equation true is equal to: B. p = -5

<u>Given the following equation:</u>

  • 3p - 8 = -23

To find a value of p that makes the given equation true:

In this exercise, you're required to determine a value of p that satisfies the given equation true such that when substituted into the equation, it has a true result or outcome.

Rearranging the equation by collecting like terms, we have:

3p - 8 = -23\\\\3p=-23+8\\\\3p=-15\\\\p=\frac{-15}{3}

p = -5
