Answer:

I think it is 4 or 104. There are 2 ways to look at it.

Way #1:

50 + 50 = 100

100 - 25 = 75

75 x 0 = 0

2 + 2 = 4

0 + 4 = 4

Way #2:

50 + 50 = 100

25 x 0 = 0

100 - 0= 100

2 + 2 = 4

100 + 4 = 104

Answer:

C. 168°

Step-by-step explanation:

The exterior angle at any vertex of an n-gon will be ...

360°/n

So a 30-gon will have exterior angles of ...

360°/30 = 12°

The adjacent interior angle is supplementary to this, so is ...

180° -12° = 168°

_____

Using the reasonableness test

You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.

Your teacher announced a 50-point math quiz for tomorrow. The quiz will have 15 questions with word problems worth 4 points each

koban [17]

Answer:

5 word problems(4points each) & 10 open (3 points each)

Step-by-step explanation:

O= open response

W= word problems

W+O =15

4W + 3O = 50

multiply the first by -3 to eliminate O

-3W -3O = -45

4W + 3O = 50

AD BOTH

W = 5 ( 5 questions word problems)

O= 10 ( 10 questions open response)

5x4 = 20

10x3 = 30

20 + 30 = 50 points

I'm lowkey bout to have a heart attack if I don't get a tutor :(

allochka39001 [22]

Answer:

5(2x + 6) = -4(-5 -2x) + 3x

10x + 30 = 20 + 8x + 3x

10x + 30 = 20 + 11x

Applying the additive inverse property, we get,

10x + 30 - 10x - 20 = 20 + 11x - 10x - 20

10 = x

Which expression is equivalent to Assume x > 0 and y 0.

Svetach [21]

we have

$\sqrt{\frac{55x^{7}y^{6}}{11x^{11}y^{8}}}$

we know that

$\sqrt{\frac{55x^{7}y^{6}}{11x^{11}y^{8}}} =\sqrt{\frac{55}{11}\frac{x^{7}}{x^{11}}\frac{y^{6}}{y^{8}}} \\ \\= \sqrt{\frac{5}{x^{4} y^{2}}} \\ \\ =\frac{\sqrt{5}}{x^{2} y}$

therefore

the answer is

The expression equivalent is $\frac{\sqrt{5}}{x^{2} y}$
