Answer:
= z/12 - 1/3
Step-by-step explanation:
z-4/(4+8)
= z-4/12
= z/12 - 4/12
= z/12 - 1/3
Answer:
Option B.
Step-by-step explanation:
In the given events lets find out the event that has a probability other than 1/2.
A. Flipping a coin gives result of head or tail, so the probability of the result of tails is 1/2.
B. Choosing a vowel from a bag of tiles that contains one of each letter of the alphabet, so the probability of choosing vowel is 5/26.
C. A cube that has numbered from 1 to 6, there are 3 even numbers and 3 odd numbers, so the probability of rolling even number is 3/6 or 1/2.
D. There is 26 red cards in a standard deck of 52 cards, so the probability of choosing red card is 26/52 or 1/2.
Therefore, events A, C and D gives result of 1/2 and B other than 1/2
So Option B is the correct answer.
<u>1 + 4x = -5 + 7x</u>
1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:
1+5=7x-4x
2nd step:
3x=6
3rd step: you need to divide both sides into 3, because it is the common divisor.
x=2
<h2>
To sum up:</h2>
<em>1 + 4x = -5+7x</em>
<em>7x - 4x = 1 + 5</em>
<em>3x = 6</em>
<h2>
<em>x = 2</em></h2>
You can try to memorize the summary. However, it is better to understand the solution as a whole.
