Find the value of X. WILL GIVE BRAINLIEST!

Mathematics
1 answer:
Sveta_85 [38]2 years ago
8 0

Answer:

36

Step-by-step explanation:

Angles in a triangle sum to 180 degrees.

The angle in the bottom left will equal 180 - (3x + 6) as angles along a staight line also sum to 180 degrees.

180 - ( 3x + 6)

180 - 3x - 6   [expand bracket]

174 - 3x

Now we can add up all the angles and equate them to 180 to solve for x.

24 + 2x + 18 + 174 - 3x = 180

216 - x = 180

216 = 180 + x

x = 36

Solve by using elimination. Express your answer as an ordered pair.
olga55 [171]

Greetings.

The answer is (5,4)

Explanation:

Solving by elimination can be done by adding or subtracting of first and two equation.

Find any terms that make themselves = 0.

And that is the y-term.

Our 2y and -2y. If we add each others, we'd get 0 for y-term.

Therefore, we eliminate the y-term first.

\left \{ {{-x+2y=3} \atop {3x-2y=7}} \right. \\2x=10

If you are wondering how I get 2x = 10 then here's the explanation.

So we simply add/subtract both equations.

We do -x + 3x = 2x

Then +2y - 2y = 0

And 3 + 7 = 10

That's how we get 2x = 10.

Basically Add/Subtract in Vertical way.

2x=10\\x=5

We may get the x-value but we need to know the y-value too.

Therefore, substitute x = 5 into any given equations. I suggest you to substitute the x-value in any equations with less coefficient value.

I'd rather substitute x = 5 in -x+2y = 3.

-x+2y=3

Substitute x = 5 in -x + 2y = 3

-5+2y=3\\2y=3+5\\2y=8\\y=\frac{8}{2}\\y=4

Therefore, when x = 5, y = 4. Since you want the answer in ordered pairs then It's (5,4).

5 2/5 divided by 9/10
Fed [463]

Answer:

Step-by-step explanation:

5 2/5 = [(5*5)]+2 / 5 = (25+2) / 5 = 27/5

(27/5)/(9/10) = 27/5 * 10/9

cross cancel 27 becomes 3 and 9 becomes 1, 5 becomes 1 and 10 becomes 2

= 3/1 * 2/1 = 6/1 = 6

HELP PLEASE HELP!!!!!!!
Ket [755]
If we are to write this equation in slope-intercept form, it will be in y = mx + b, where m is the slope of the line and b is the y intercept.  We need then to find the slope of the line using 2 points on the line and filling in the slope formula to find the slope.  One of the points we can use is (0, 3) which is also the y intercept.  The y-intercept is found where x = 0.  Where x = 0, y = 3.  So b = 3.  Now for the slope we will use (0,3) and (4,4):  m= \frac{4-3}{4-0} = \frac{1}{4}.  Using that m value and that b value we have the equation y= \frac{1}{4}x+3.  There you go!
