Answer:

x = 27/10 or x = 2.7

Step-by-step explanation:

Step 1: Get rid of the denominator.

LCD of 4 & 3: 12

Multiply both sides by 12.

12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)

Reduce the numbers.

3 ( 2x - 1) + 4x = 24

Step 2: Distribute.

6x - 3 + 4x = 24

Step 3: Collect like terms.

6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)

10x = 27

Step 4: Solve for x.

Multiply both sides by 10.

10x / 10 = 27 / 10 (the 10 cancels out)

x = 27 / 10 or x = 2.7

Answer: x = 27 / 10 or x = 2.7

What is the theoretical probability of rolling an odd number on a fair die with six faces?
tensa zangetsu [6.8K]
In a die, there are 3 odd numbers, specifically: 1, 3 and 5.
In probability for a certain event, it is a ratio of the number of favorable outcomes over the total number of possible outcomes.

Since we have 3 favorable outcomes and 6 total possible outcomes, thus
P = 3/6 = 1/2 (in lowest term)
