Does anyone know how to do this

Answer:
m+n=140
Step-by-step explanation:
While it may seem you need to find the measure of m and n, you don't. Looking at the angle with measure of 40 degrees you can see inside the triangle that the top angle is congruent to the angle of 40 degrees. Now that you know that the top of the angle is 40 degrees then knowing a triangle is 180 degrees total you can infer that m+n=140 because adding 140 to 40 is also 180.

B. 4n + 11 < -9
C. -4n +11 < -9
D. -4n + 11 > -9
(Please show your work:) )
Answers
(Subtract 11 from both sides)
4n > -20
(Divide both sides by 4)
n > -5
Because we have found that dividing the negative number by 4 does not work, we know B is also wrong.
Not C because:
(Subtract 11 from both sides)
-4n < -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n > 5
So, it must be D!
Here's why:
(Subtract 11 from both sides)
-4n > -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n < 5
Hope this helps!
4n + 11 > -9
4n > -9 - 11
4n > -20
n > -20/4
n > -5
This does not give the required solution of n < -5
B would give n < -5, this would also not be correct.
Let us try option C
-4n + 11 < -9
-4n < -9 -11
-4n < -20
n > -20/-4 since we divided by -ve, the sign changes.
n > 5 this does not give the answer as well.
-4n + 11 > -9
-4n > -9 -11
-4n > -20
Divide both sides by 4 and the sign changes.
-4n/4 < -20/-4
n < 5
This is the required solution. So option D gives that solution.
Hope this helps.

Well, I actually did the entire calculations until I figured out that its very simple, and I didn't need to!
If she has already saved 6%, then to find how much she still needs to save, we subtract 100% from 6%.
So Nina still has to save 94% of the total cost to get the bike.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6) ------> 6x - 15 = 6x - 18
Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.

The difference between 2,386 and 7,000 is 4614. So, option (B) s correct.
The opposite of an operation is an inverse operation. They are the procedure that undoes the results of another procedure.
For instance, multiplication is the inverse operation of division, and addition is the inverse operation of subtraction.
To calculate the difference between 2386 and 7000.
Subtract 2386 from 7000 as follows:
7000-2386=4614.
To check the answer, we can apply the inverse operation of subtraction, which is addition. So add 4614 to 2386 we get as follows:
4614+2386=7000
Thus, this confirms the difference to be 4614. So, option (B) s correct.
