Regroup terms

2 = 7x - 3

Add 3 to both sides

2 + 3 = 7x

Simplify 2 + 3 to 5

5 = 7x

Divide both sides by 7

5/7 = x

Switch sides

<u>x = 5/7</u>

We have three coins: one with heads on both faces, the second with tails on both faces, and the third a regular one. We choose o
Finger [1]

Answer:

Probability: \frac{1}{2} = 0.5 = 50%

Step-by-step explanation:

Based on the question one coin is chosen at random and tossed. That coin then lands and is heads. Since the coin landed on heads we can <u>eliminate the possibility</u> of the coin that was chosen being the coin with double tails.

The following possibilities are that the coin has double heads or is a regular coin with both tails and heads. Seeing as the coin landed on heads, there are only two possible out comes for the other side of the coin

The other side is either Heads or Tails. That gives us a 50% chance of the other side being tails.

\frac{1}{2} = 0.5 = 50%

2. For a particular model of a car, a dealer offers 3 sizes of engines, 2 types of stereos, 18 body
Gnesinka [82]

The given details follow the product rule. The different model of the car available are 756.

Given that:

Engines = 3

Stereos = 2

Body=18

Color = 7

The different possibility is calculated using the following product rule:

Total =Engines \times Stereos \times Body \times Color

So, we have:

Total = 3\times 2\times 18 \times 7

Total = 756

Hence, there are 756 different models available.
