-7x ≥ 56.
Divide both sides by -7, and the inequality sign reverses, because we are dividing by a negative number.
The sign also reverses when you multiply both sides of inequality by a negative number.
-7x/-7 ≤ 56/-7
x ≤ -8
The answer is the first option.
<span>{x | x ≤ -8}
</span>
This simply means x, such that x is less than or equal to -8.
I hope this helped.
Answer: The filled out table is shown below in the attached image
===========================================================
Explanation:
The letters A through J are one way to fill out the table. Though there are other possible orders.
Start at letter A, which is from the fact we have 40 people total
Then move to letter B. This is the total number who like pasta (26)
We have C = A-B = 40-26 = 14 people who don't like pasta
--------------
Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.
F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.
Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.
----------------
So we have these values
- A = 40
- B = 26
- C = 14
- D = 21
- E = 19
- F = 4
- G = 17
- H = 9
- J = 10
Your answer would be 18.39
And here's why:
Behind the decimal your numbers are in the following places.
The (3) is in the tenths place.
The (8) is in the hundredths place.
And the (6) is in the thousandths place.
Whatever number is AFTER the place your rounding, is going to help you out.
If the number is 1-4, you round down.
If the number is 5-9, you round up.
