Answer:

<h3>hello there!</h3>

$\left|5\right|+\left|-7\right|$

$rule =a,\:a\ge 0$

$|5|=5$

$\mathrm{Apply\:absolute\:rule}:\quad \left|-a\right|=a$

$\left|-7\right|=7$

$5+7=$

$12$

hope this helps you..

Answer:

The value of x is 9°

Step-by-step explanation:

The given parameters are;

ΔUVW with side UW extended to X

m∠UVW = (3x + 4)°

m∠VWX = (8x -12)°

m∠WUV = (x + 20)°

We have that m∠UVW + m∠WUV + m∠VWU = 180° (Sum of the interior angles of a triangle theorem)

∴ m∠VWU = 180° - (m∠UVW + m∠WUV)

Also we have that m∠VWX and m∠VWU are supplementary angles, (The sum of angles on a straight line)

∴ m∠VWX + m∠VWU = 180° (Definition of supplementary angles)

m∠VWU = 180° - m∠VWX

∴ m∠VWX = (m∠UVW + m∠WUV)

Substituting the values, gives;

(8x -12)° = (3x + 4)° + (x + 20)°

8x - 3x - x = 4 + 20 + 12

4x = 36

x = 36/4 = 9

x = 9°.

Add the fractions and simplify 5 2/5 + 2 10/13=

HACTEHA [7]

Simple....

you have:

$5 \frac{2}{5} +2 \frac{10}{13}$

to convert them into improper fractions:

1.) Take whole number*denominator

(5*5=25)

2.) Take what you got...and add the numerator

(25+2=27)

3.) Use the original denominator

$\frac{27}{5}$

Do the same to the other one...

2*13=26

26+10=36

$\frac{36}{13}$

Now..add...

$\frac{27}{5} + \frac{36}{13}$

But..you need a common denominator!

$\frac{27}{5} * \frac{13}{13}= \frac{351}{65}$

$\frac{36}{13} * \frac{5}{5} = \frac{180}{65}$

Now you can add!

$\frac{351}{65} + \frac{180}{65} = \frac{531}{65}$

When simplified....

$8 \frac{11}{65}$

Thus, your answer.

Is a || b? Explain using angle measurements. Your response should contain at least 3 full sentences describing how you determine

aliya0001 [1]

Answer:

Step-by-step explanation:

Angles 6 and 9 are alternate interior angles where transversal 'a' crosses parallel lines p and q. As such, they are congruent. This means the measure of angle 6 is the same as that of angle 9, 110°.

Angles 6 and 8 are <em>corresponding</em> angles. If lines 'a' and 'b' were parallel, those angles would be congruent. We know angle 6 has a measure of 110° and angle 8 has a measure of 70°, so the angles are not congruent. Hence, lines 'a' and 'b' are not parallel.

<em>Alternate solutions</em>

Since you are not allowed to plagiarize my answer, you may be interested in other ways to show the same thing. The basic idea is to use angle relationships where transversals cross parallel lines. Ones that can be useful here are ...

corresponding angles are congruent
vertical angles are congruent*
alternate interior (or exterior) angles are congruent
sequential interior (or exterior) angles are supplementary.
angles of a linear pair are supplementary*

The relations marked with an asterisk (*) apply where <em>any</em> lines cross, and have no specific relationship to parallel lines. The remaining relationships only occur if the lines are parallel. Showing one of those is not true will show that the lines are not parallel.
