Answer:

82 degrees

Step-by-step explanation:

1. Measure of angle BAD + ABC = 180 degrees (definition of a parallelogram). Because ABC = 71, and CAD = 27, you get BAC + 71 +27 = 180. --> BAC = 82 degrees

2. BE * 2 = BD. This means that 2(2x+2) = 5x-3. This means 4x + 4 = 5x-3, which makes x = 7. AC = 2AE, which means that 2(4x-6) = AC, which means AC is 2(28-6), which makes AC = 44.

3. Because MNPQ is isosceles, NMQ = PQM. This also means PQM +NPQ = 180. NMQ = 30 +32 = 62. This makes NPQ + 62 = 180. NPQ = 118

Solve the system of equations -12x-5y=40 12x-11y=80

Gwar [14]

Answer:

The answer is (-5/24, -7.5).

Step-by-step explanation:

There are two methods to solving a system of equations - substitution or elimination. In this example, we can use elimination since the coefficients of 'x' are opposite signs. To complete elmination, we simply add the equations together:

-12x - 5y = 40

+ 12x - 11y = 80

-16y = 120

Use inverse operations to solve for 'y' by dividing both sides by -16 to get y = -7.5.

Next, plug in the value of 'y' into one of the equations and solve for 'x':

-12x - (5)(-7.5) = 40 or -12x + 37.5 = 40, now subtract 37.5 from both sides: -12x + 37.5 - 37.5 = 40 - 37.5 or -12x = 5/2. Lastly, divide both sides by -12 to solve for x, x = -5/24.

Someone just answer this math question thingie lol. you’ll get 33 points G

Stels [109]

1) $(-2x+4)+(x-6)$ is simplified into $=-x-2$

2) $(uv-3)+(4uv+1)$ is simplified into $5uv-2\\$

3) $(11x-8)-(2x+3)$ is simplified into $-9x-11$

4) $(x^2-4)-(x-2)$ is simplified into $x^2-x-2$

5) $(12-3t-7t^2)+(1+3t-t^2)$ is simplified into $-8t^2+13$

Step-by-step explanation:

We need to solve the polynomials.

1) $(-2x+4)+(x-6)$

Solving:

$(-2x+4)+(x-6)\\=-2x+4+x-6\\Combining\,\,like\,\,terms:\\=-2x+x+4-6\\=-x-2$

So, $(-2x+4)+(x-6)$ is simplified into $=-x-2$

2) $(uv-3)+(4uv+1)$

Solving:

$(uv-3)+(4uv+1)$

Expanding:

$=uv-3+4uv+1\\Combining\,\,like\,\,terms:\\=uv+4uv-3+1\\=5uv-2\\$

So, $(uv-3)+(4uv+1)$ is simplified into $5uv-2\\$

3) $(11x-8)-(2x+3)$

Solving:

$(11x-8)-(2x+3)$

Expanding:

$=11x-8-2x-3\\Combining\,\,like\,\,terms:\,\,\\=11x-2x-8-3\\=-9x-11$

So, $(11x-8)-(2x+3)$ is simplified into $-9x-11$

4) $(x^2-4)-(x-2)$

Solving:

$(x^2-4)-(x-2)$

Expanding:

$=x^2-4-x+2\\Combining\,\,like\,\,terms:\\=x^2-x-4+2\\=x^2-x-2$

SO, $(x^2-4)-(x-2)$ is simplified into $x^2-x-2$

5) $(12-3t-7t^2)+(1+3t-t^2)$

Solving:

$(12-3t-7t^2)+(1+3t-t^2)$

Expanding:

$=12-3t-7t^2+1+3t-t^2\\Combining\,\,like\,\,terms:\\=12+1-3t+3t-7t^2-t^2\\=13+0t-8t^2\\=-8t^2+13$

So, $(12-3t-7t^2)+(1+3t-t^2)$ is simplified into $-8t^2+13$

How does the setting of a story influence a characters feelings and actions?

Ratling [72]

Answer + Step-by-step explanation:

Settings can affect the character in a number of ways.

For example, it can cause conflict and influence the character's

actions. In the setting of a war, it will obviously cause conflict

for a character or change the character's attitude towards another

character whom they probably knew well. The setting can affect the mood

and tone of the scene, resulting in many actions the reader did not think was

going to happen before.
