Answer:

C. 100°

Step-by-step explanation:

Hello, great question. These types are questions are a great step for learning more advanced Geometric Equations.

Since we are working with a parallelogram we should first know the properties that this figure has. The properties are the following

  • <u><em>Opposite sides</em></u> are equal to each other
  • <u><em>Opposite angels</em></u> degrees are equal to each other
  • Angles next to each other equal 180° when added
  • If one angle is 90°, then all angles are 90°.

Based on the properties of a parallelogram shown above we can see that 80° and x are next to each other so their <u><em>sum should equal</em></u> 180°. Since this is the case we use this to solve for x like so,

80+x = 180 .... subtract 80 on both sides

x= 100

Finally we can see that the value of x is 100° so the answer would be C.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Allison’s cupcake and cookie budget for her party is $105. She would like to have at least 40 cupcakes and cookies combined, and
FinnZ [79.3K]

Answer:

a + b ≥ 40

a + 5 ≤ b

2.50a + 1.50b ≤ 105

Step-by-step explanation:

We are told she would like to have at least 40 cupcakes and cookies combined.

If a is number of cupcakes and b is number of cookies, then this inequality is;

a + b ≥ 40

Secondly, we are told she would like to have at most 5 more cupcakes than cookies.

Thus, the inequality is;

a + 5 ≤ b

Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50

Thus, the inequality is;

2.50a + 1.50b ≤ 105

Finally, the 3 inequalities are;

a + b ≥ 40

a + 5 ≤ b

2.50a + 1.50b ≤ 105

Answer:

50=(3x)x

Step-by-step explanation:

50=(3x)x. The question is only asking for the inequality of the problem. Since the area of a rectangle is L x W, you would write L as 3x and W as x, and since the area of the rectangle is given, you can set the area as 50.
