Answer:

The answer to your question is x = 40°

Step-by-step explanation:

According to the picture we determine that the triangle to the right is  isosceles so two of its angles are equal.

Remember that the sum of the internal angles in a triangle equals 180°

                            2x° + 100° = 180

- Subtract 100 in both sides

                            2x + 100 - 100 = 180 - 100

- Simplify

                            2x = 80

-Divide both sides by 2

                            2/2 x = 80/2

Simplify and result

                                  x = 40°

olga_2 [115]

The system of inequalities is x+y≥250 and 3x+2y≤800.

Step-by-step explanation:

Given,

People to invite = at least 250

At least 250 means that the number can increase from 250.

Cups to be provided = only 800

It means the number cannot exceed 800.

Number of adults = A

Number of children = C

According to given statement;

x+y≥250

3x+2y≤800

The system of inequalities is x+y≥250 and 3x+2y≤800.

How to factor 18a2+6a5-8a3
Zielflug [23.3K]

Answer:

2a^2(3a^3-4a+9)

Step-by-step explanation:

You could change the equation to this: 6a^3a^2-8a^1a^2+18a^2

*This is the exact same as 18a^2+6a^5-8a^3

You can continue to break this down until you get:

2*3a^3a^2-2*4a^1a^2+2*9a^2

*This too = 18a^2+6a^5-8a^3

With this new equation, you can cancel out the common term: 2a^2

You come up with my answer.

<em>Hope this helps!!</em>
