Answer: A, and E

Step-by-step explanation:

x is anything less than -200. Because youre in the negatives you have to think about it backwards. -120 is closer to 0 same with 102 and because x isnt less than or equal to -200, its not an answer either

Answer 2

Answer:{x|x<-200}

Let’s take a look at each of the choices:

A. Does 275-232+132=275?
175 ❎

B. Does 275+278-278=275?

C. Does 275-115+312=275?
472 ❎

D. Does 275+205-317=275?
163 ❎

The correct answer is B

The logical way to think about this is that adding 278 and then taking out 278 cancels the action. -278+278=0, indicating that no change has been made

77 PTS!! On the following composite figure, all angles are right angles. All short edges of the figure have a measure of 1.5 centimeters. All long edges have a measure of 3 centimeters. Find the area of the figure. Explain or show how you got your answer.

Answers

Answer:Answer:

 27 cm²

Step-by-step explanation:

There are many ways the figure can be decomposed into parts for which you know the area formula. The total area is the sum of the parts.

__

decomposition

We recognize that each of the tabs is twice as long as wide, so is half a square. The 4 tabs together make 2 squares that are 3×3 cm. Of course, what remains after removing the tabs is a 3×3 cm square in the middle of the figure.

sum of parts

Then the total area is that of 3 squares measuring 3 cm × 3 cm:

 A = s² = (3 cm)² = 9 cm² . . . . . area of one square

 total area = 3A = 3(9 cm²) = 27 cm²

The area of the figure is 27 cm².

This depends on your definition of close.

Rational numbers are numbers that can be written as p/q where p and q are integers and q is not 0. Examples include 22/7 or 1 or 0.5.

Irrational numbers are not rational. Example include pi or square root of 2.

Two rational numbers close to -8 could be -9 and -25/3. Two irrational numbers could be -e and [tex]-5\sqrt{2}[/tex].

Then the order goes -9,-25/3 (since it is -8.333...),[tex]-5\sqrt{2}[/tex] (root 2 is around 1.4 so it is near -7),-e(around -2.7)

Answers

When two angles are supplementary, it means that the two angles add up to 180°.
Thus when angle m is 34° and angle n is (2x)° when angle m and angle n are supplementary,

angle m + angle n = 180°
34° + (2x)° = 180°

*minus 34° on both sides of the eqn*

(2x)° = 180°-34°
(2x)° = 146°

To find x, divide both sides of the eqn by 2
x= 146°/2
x= 73°

I hope this helps! Feel free to clarify if you have any questions!

The value of x is:

↬ 73

Solution:

If two angles are supplementary, that means that the sum of their measures is 180°.

We're given 2 angles:

[tex]\sf{\angle m}[/tex][tex]\sf{\angle n}[/tex]

And since they're supplementary, the following holds true:

[tex]\sf{\angle m + \angle n = 180}[/tex]

Next, we know that [tex]\sf{\angle m=34}[/tex], so we plug that in

[tex]\sf{34+\angle n = 180}[/tex]

Then, ∠n = 2x:

[tex]\sf{34+2x=180}[/tex]

Which is the same as

[tex]\sf{2x+34=180}[/tex]

Subtract 34 from each side

[tex]\sf{2x=146}[/tex]

Divide each side by 2

[tex]\sf{x=73}[/tex]

Hence, x = 73
