Answer:
x = 9
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
[tex]7x - 4x = 4x + 27 - 4x[/tex] [tex]3x = 27[/tex]Step 2: Divide both sides by 3.
[tex]\frac{3x}{3} =\frac{27}{3}[/tex] [tex]x = 9[/tex]Step 3: Check if solution is correct.
[tex]7(9) = 4(9) + 27[/tex] [tex]63 = 36 + 27[/tex] [tex]63 = 63[/tex]Therefore, x = 9.

The difference of the Expression is (x -1) / (x² + 3x + 2).
What is Expression?In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows:
(Number/variable, Math Operator, Number/variable) is an expression.
We have,
x/ (x² + 3x + 2) - 1/ (x+ 2)(x+ 1)
Now, simplifying the expression as
x/ (x² + 3x + 2) - 1/ (x+ 2)(x+ 1)
= x/ (x² + 2x + x + 2) - 1/ (x+ 2)(x+ 1)
= x/ x(x+ 2) + (x+ 2) - 1/ (x+ 2)(x+ 1)
= x/ (x+2) (x+1) - 1/ (x+ 2)(x+ 1)
= (x-1) / (x+ 2)(x+ 1)
= (x -1) / (x² + 3x + 2)
Thus, the difference of the Expression is (x -1) / (x² + 3x + 2).

Answer:
one solution; (x, y) = (4/3, 11/3)
Step-by-step explanation:
The two lines described by the equations have different slopes, so there will be exactly one solution to the system of equations.
__
The slope of the line will be the coefficient of x when you solve for y. In the first equation, the slope is 2. In the second equation, you can solve for y by adding x, and dividing by 2. Then the slope of that line is found to be 1/2.
Lines with different slopes must intersect somewhere. That point of intersection is the (one) solution to the system of equations.

Backstory)) Today as I was waking to lunch with a few people that were my so called friends, they are in the dance team and they wanted to go and help sell tickets there was one small table to sell tickets. But the thing is that there is only room for about 4 people on that table but they fit 7 which logically I think we all know that 7 people don’t need to sell tickets, only if 2 people actually bought tickets
So as we entered the cafeteria I followed them (I am not on the dance team) they went to that very table then I asked the obvious question where should I sit? Cause there want room for me. Then one of my friends pointed at an empty table and told me to sit there. I sit there the whole lunch eating only a few. I am stressed when nobody is next to me eating which causes me to eat less. Cause I feel everyone is staring at me. So I act like I am fine. Then after that we had some free time. I went to the bathroom the whole free time to just cry. But the thing is as the free time started they didn’t come and get me they just walked off so that’s why I went to the restroom and stayed in there for a little till the bell rang.
So what should I do they are going to do the same thing tomorrow and I am getting stressed cause I have no other friends to sit with.
Answer: I would see the councilor and see if that can help thats what I did they gave me option and I also could have had a pass to eat with a teacher or I could eat in there office :)

Contains (5,8) and is parallel to the graph of 2x + 3y = 9.
Answer:
[tex]\displaystyle y = -\frac{2}{3} x + \frac{34}{3} \text{ or } 2x + 3y =34[/tex]
Step-by-step explanation:
We want to find the equation of a line that contains the point (5, 8) and is parallel to the graph of:
[tex]\displaystyle 2x + 3y = 9[/tex]
Recall that parallel lines have equal slopes.
Find the slope of the given graph by rewriting it in slope-intercept form:
[tex]\displaystyle \begin{aligned} 2x + 3y & = 9 \\ \\ 3y & = -2x + 9 \\ \\ y & = -\frac{2}{3} x + 3 \end{aligned}[/tex]
Hence, the slope of the given graph is -2/3. Therefore, the slope of our new line must also be -2/3.
Since we now have a slope and a point, we can consider using the point-slope form:
[tex]\displaystyle y - y_1 = m(x-x_1)[/tex]
Substitution yields:
[tex]\displaystyle y - (8) = -\frac{2}{3}(x -( 5))[/tex]
We can simplify this into slope-intercept form:
[tex]\displaystyle \begin{aligned} y - 8 & = -\frac{2}{3} x + \frac{10}{3} \\ \\ y & = -\frac{2}{3} x + \frac{34}{3}\end{aligned}[/tex]
Or, into standard form:
[tex]\displaystyle \begin{aligned} y & = -\frac{2}{3}x + \frac{34}{3} \\ \\ 3y & = -2x + 34 \\ \\ 2x + 3y & = 34 \end{aligned}[/tex]

Six columns shaded vertically and one row shaded horizontally. The intersection is 6 grid blocks. D. Hundred grid. Eight columns shaded vertically and three rows shaded horizontally. The intersection is 24 grid blocks.
Answer:
B
Step-by-step explanation:
It seems like the answer would be B since 0.4 x 0.9 = 0.36 and the intersection for answer choice B is 36 grid blocks.
The correct equation of the given grids models the problem is,
⇒ Hundred grid. Four columns shaded vertically and nine rows shaded horizontally. The intersection is 36 grid blocks.
Option B is true.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Bailey wants to find the value of 0.4 × 0.9.
Now,
After multiplication, we get;
⇒ 0.4 × 0.9
⇒ 0.36
Hence, By all the options;
The correct equation of the given grids models the problem is,
⇒ Hundred grid. Four columns shaded vertically and nine rows shaded horizontally. The intersection is 36 grid blocks.
Option B is true.

Janice is a travel agent. She receives a 7% commission based on the value of the trips she
books. Today she spent 5 hours arranging a $6,300 cruise for a couple.
Based on her commission percentage, Janice was able to earn $441 in commission which translates to $88.20 per hour
The commission that Janice earned is found by:
= Commission percentage x Value of trip booked
= 7% x 6,300
= $441
The amount she earned per hour is therefore:
= Commission earned / Number of hours worked
= 441 / 5
= $88.20
In conclusion, Janice earned $441 in commission and earned $88.20 per hour.

23 in. The perimeter of this quadrilateral is 100 in. What is the length of the side not given? 27 In. 32 in.
Answer:
Solution:
The formula to find the perimeter of the quadrilateral = sum of the length of all the four sides.
Here the lengths of all the four sides are 5 cm, 7 cm, 9 cm and 11 cm.
Therefore, perimeter of quadrilateral = 5 cm + 7 cm + 9 cm + 11 cm
= 32 cm
