At a DBE lecture of 100 students there are 29 women and 23 men. Out of these students 4 are teachers and 24 are either men or te
Anika [276]

Answer:

The number of women teachers attending the lecture is 1

Step-by-step explanation:

Let M denotes men , W denotes women and T denotes teachers.

Number of women = n(W)=29

Number of men = n(M)=23

Number of teachers=n(T)=4

We are given that 24 are either men or teachers.

So,n(M∪T)=24

We are supposed to find the number of women teachers attending the lecture. ​

n(M∪T)=n(M)+n(T)-n(M∩T)

24=23+4-n(M∩T)

n(M∩T)=3

So,No. of teachers those are men is 3

Total number of teachers = 4

So,  the number of women teachers attending the lecture= 4-3 = 1

Hence the number of women teachers attending the lecture is 1

How do I solve for -31 -8r = -3(5r -6)
Dennis_Churaev [7]
Our current equation is:
-8r -31 = -3(5r -6)
To solve for this, we need to get r on one side of the equation and then simplify if needed.
On the right side of the equation, we have a pending Distributive Property, which is when you multiply the number/variable outside of the parenthesis by all numbers/variables in the parenthesis.
Let's simplify this Distributive Property to help understand our equation better.
-3(5r -6)
Multiply -3 by each number/variable separately (unless they are already being multiplied, like 2x, 1/2x, etc).
-3(5r) + -3(-6).
-3(5r) = -15r
-3(-6) = 18 (both negatives need to be in parenthesis to keep a product as negative, and if you do not multiply them in that way, you will end up with a positive product).
Your equation now is:
-8r -31 = -15r + 18
Add 15r to both sides to get r on one side.
7r -31 = 18 is now our current equation.
Add 31 to both sides to get 7r by itself.
7r = 49 is now our equation.
r is still being multiplied by 7, so we need to do the opposite of multiplying by 7.
Divide both sides by 7.
r = 7.
I hope this helps!
