1. Distribute the 9.

27x - 144 + 15 = 6x - 24

2. Combine like terms

27x - 129 = 6x - 24

3. Gather all the terms with x on the left, and all the constants on the right. We do this by subtracting 6x and adding 129 to both sides.

21x = 105

4. Divide both sides by 21

x = 21

So, x = 21 makes the equation true.

You and your friend play a game. You answer 80% of the questions correctly and your friend answers 0.60 of the questions correct

bezimeni [28]

Answer:

Step-by-step explanation:

Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.

Let x be the number of questions, solving by trial and error:

$if\ x=2\\x*0.8=1.6\\x*0.6=1.2\\\\if\ x=3\\x*0.8=2.4\\x*0.6=1.8\\\\if\ x=4\\x*0.8=3.2\\x*0.6=2.4\\\\if\ x=5\\x*0.8=4\\x*0.6=3\\\\$

Therefore, the minimum number of questions in the game is 5.
