Answer: -4/6 or -2/3
Step-by-step explanation:
First, you find a common denominator among the fractions, which would be 6.
Convert -1/2 to have 6 as its denominator.
-1/2* 3/3 = -3/6
And then subtract them.
-3/6 - 1/6 = -4/6
-4/6 simplified is -2/3
When you subtract a positive number from a negative number, you are adding their absolute values.
Answer:
m=-5
Step-by-step explanation:
You first do distributive property:
(-m*-1)+(-1*-7)+(-3*4m)+(-3*-3)=71
that simplifies to:
16-11m=71
Next subtract 16 on both sides and you get:
-11m=55
Then divide by -11,
m=-5
This is a classic problem I think that you mean
Answer:
This problem clearly states to use proof by induction, follow the complete answer below.
Step-by-step explanation:
To prove something by induction we have to make a proposition first, in this case:
is divisible by 9
Where is the order of the proposition.
First we have to prove the first few orders, let's just check P(1):
which is clearly divisible by 9
Now let's assume that P(n) is true that means, our original proposition is true. Now let's try to find out whether P(n+1) is true:
The is divisible by 9 because we assumed that " is divisible by 9" was a true proposition. On the other hand has a factor of 9 regardless of n, thus is also divisible by 9 that means that P(n+1) is true and it follows that P(n) must also be true, thus proving our initial statement.
The answer to your question is 55.93
Step-by-step explanation:
So for this question just substitute the value and work out. I thought it it to the power of 2 as I can't tell from the question.
