X=10
-8-x=-3(2x-4)+3x
-8-x=-6x+12+3x
-8-x=-3x+12
-x+3x=12+8
2x=20
x=10
You can check your solution by inputting 10 in all the x’s and solving it:)

Which of the following shows the graph of the eniquality y&gt;x+3<br><br> PLEASE include image
7nadin3 [17]

in plain and short, to graph an inequality, we first graph its EQUALITY graph, and then we do the shading.

so to graph y > x + 3, we first graph y = x + 3, which is just a line, and then do a true/false check on a point to see which side we shade.

let's hmmm  check the point say (0,2), x = 0, y = 2.

y > x + 3

2 > 0 + 3

2 > 3  <--- is that true?  is 2 really larger than 3?  nope, so is false.

that simply means that the point (0, 2)  is on the false area, so that's the area we do NOT shade, so <u>we shade the other side</u>.

y > x + 3, means "y" is greater than or larger than that line, but not equals, larger not equal, meaning the values on the borderline are not included, so the line is a dashed line.


check the picture below.

Angle A=11x-4, Angle B = 4x-11, and Angle C=63-4x. List the sides of triangle ABC in order from shortest to longest.
romanna [79]
1. The sum of of the interior angles of a triangle is 180°.

 2. Keeping this on mind, you have:

 A+B+C=180
<span>
 A=11x-4
 B = 4x-11
 C=63-4x
</span>
 3. When you substitute these values, you obtain:

 A+B+C=180
 11x-4+4x-11+63-4x=180
 11x+48=180
 11x=180-48
 11x=132
 x=132/11
 x=12

 3. Therefore:

 A=11(12)-4
 A=128°

 B = 4(12)-11
 B=37°

 C=63-4(12)
 C=15°

 5. The answer is:

 A. AB, AC, BC

A stadium can seat 16,000 people at full capacity. If there are 13,920 people in the stadium, what percentage of the capacity is
Soloha48 [4]

Answer:

87%

Step-by-step explanation:

In order to get 87% you divide 16000 by 13920

16000/13920= 0.87

To convert this into a percentage you can multiply by 100

0.87 * 100 =87

Answer: 87%

I hope this helps :)

Pt. 1- Write an algebraic expression that Marshall
Goshia [24]

Answer:

The answer is that the cost will be a total of $142.05. That is $125.80 for Watermelon that weighs 185 lbs and $16.25 for 5 lbs of tomatoes.

Step-by-step explanation:

Given: Watermelons are .68 / lb and tomatoes are 3.25 / lb.

Let w = watermelon weight and tomato weight.

An equation would be:

.68w + 3.25t = Total cost

For 185 lb of Watermelon and 5 lbs of tomatoes:

.68(185) + 3.25(5) =

$125.80 + $16.25 = $142.05

(Hope this helps. Btw, I am the first to answer!!)
