The difference is -10 because
9-10= 1
-1-10= -11
-11-10= -21
common difference means you add and common ratios means you multiply.
hope this helps!
3/2/3 - 1/1/4
= 3/8/12 - 1/3/12
= 2/5/12
i am a mathematics teacher. if anything to ask please pm me
<span>4x - y =5
4x + 4y = -4
Change all the signs of the first equation
-4x + y = -5
Add 4x to both sides
y == 4x - 5
Substitute for y in second equation
4x + 4(4x - 5) = -4
4x + 16x - 20 = -4
20x - 20 = -4
Add 20 to both sides
20x = 16
Divide both sides by 20
x = 16/20 === 4/5
Substitute to find y
y == 4x - 5 == 4(4/5) - 5 == 16/5 - 5 = -9/5

Answer: 1/3
Step-by-step explanation: Probability is the likelihood that an event will happen.
In this problem, we want to find the probability of rolling an odd number on a standard 6-sided die.
To find the probability of rolling an odd number on a 6-sided die, we first have to think about what numbers are on a standard die.
On a standard die, we have 3 odd numbers 1, 3, and 5 and 3 even numbers 2, 4, and 6.
Since there are an equal amount of even numbers and odd numbers on a standard die, we say the probability of rolling an odd number is 3 out of 6 or 3/6 since there are 3 odd numbers and 6 total outcomes we could get. The 6 total outcomes would be all the numbers on the die.
However, we have no 3/6 on the list so we can reduce this fraction by dividing the numerator and the denominator by 3 to get the equivalent fraction 1/3. Remember, always reduce when possible when finding probability.
Therefore, the probability of rolling an odd number on a standard 6-sided die is 1/3.
