Mathematics

Whitepunk [10]4 years ago

Well first we need to do whatever is in the parentheses, which in this case is: (5x1/20)

Following the order of operations (PEMDAS) we start with the multiplication, which is (5x1). We know that 5x1=5, so now we can move on to the division:

5/20, which is equal to 0.25

So now that we know the answer to the equation in the parentheses is 0.25, we can solve the whole equation.

Here is the equation simplified:

4 (0.25)

Because there is now operation indicated between the 4 and the parentheses, we can assume that multiplication is implied, so the final equation is as follows:

4x0.25=1

The final answer is: 1

Hope this helps!

<span>Suppose U = {1, 2, 3, 4, 5} is the universal set and A = {2, 3}. What is A ?
Well "A" is {2, 3}, but I'm guessing you meant A'. 
A' is all the numbers you don't see, which is
{1, 4, 5}

4.
</span><span>Suppose U={1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P={2,4, 6, 8}. What is P?
Again, "P" is just {2,4, 6, 8}, but P' is all the numbers you don't see, which are all prime numbers in this sequence:
{1, 3, 5, 7}

5.
</span><span>-4 < k + 3 < 8
subtract 3 from all sides
-7 < k < 5

6.
</span><span> 5 <= y + 2 <= 11
subtract 2 from all sides
3 <= y <= 9

7.
</span><span>6b - 1 < -7 or 2b + 1 > 5
solve both
</span>6b - 1 < -7
add both sides by 1
6b < -6
divide both sides by 6
b < -1

now do the other problem
2b + 1 > 5
subtract both sides by 1
2b > 4
divide both sides by 2
b > 2
answer: b < -1 or b > 2

<span>8.
5 + m > 4 or 7m < -35
subtract both sides by 5 |or| divide both sides by 7
m > -5 or m < -5
m = -5</span>
