Answer:
x = 75°
Step-by-step explanation:
Sum of angles in a triangle: 180°
So,
50°+55°+x=180°
105°+ x = 180°
Subtract 105° from both sides
x = 75°
Answer:
(6ab^2)^3
Step-by-step explanation:
I believe the answer is 23/40 but I don’t have paper and pencil hope this helps
Remember distributive property, but reverse it
ab-ac=a(b-c)
a is a common factor
find common factors
factor each
9x^2=3*3*x*x
6xy=2*3*x*y
common factor is 3*x or 3x
9x^2-6xy=3x(3x)-3x(2y)=3x(3x-2y)
factored form is 3x(3x-2y)
We have 11 members at the city council meeting, 4 voted in favour of a budget increase.
The possible groups of council members who could have voted in favour can be found using the combination formula which is used when we want to group items, in this case, we are grouping people.
Here is the formula;
Where n = Total members on the city council = 11
and r = members that voted in favour = 4
We will then solve this to be

This implies that there are 330 possible groups of council members who could have voted in favour.
ANSWER: 330
