x + 7 =
X =
Answer:
x = - 11
x + 7 = -4
Step-by-step explanation:
[tex]3(x + 7) = - 12 [/tex]
Multiply each term in parentheses by 3
[tex]3x + 3 \times 7 = - 12[/tex]
Multiply 3 and 7
[tex]3x + 21 = - 12[/tex]
Move the constant to the right side and change the sign
[tex]3x = - 12 - 21[/tex]
Find the sum of negative numbers
[tex]3x = - 33[/tex]
Divide both side by the same number
[tex]x = - 11[/tex]
= x + 7
= -11 + 7
Add the term - 11 + 7

Hey ! mate
Answer:
x + 7 = -4x = -11Step-by-step explanation:
In this question we have given an equation that is 3( x + 7 ) = -12 and we have asked to find the value of x + 7 and x .
We are starting our solution from here :
[tex] \longmapsto \: 3( x + 7 ) = -12 [/tex]
Transposing 3 to right hand side :
[tex] \longmapsto \: x + 7 = \frac{ - 12}{3} [/tex]
Now , dividing -12 by 3 :
[tex] \longmapsto \: \blue{\boxed{x + 7 = -4}}[/tex]
Therefore , value of x + 7 is - 4 .Now ,
[tex] \longmapsto \:x + 7 = - 4[/tex]
Transposing 7 to right hand side :
[tex] \longmapsto \:x = - 4 - 7[/tex]
[tex] \longmapsto \: \blue{ \boxed{x = - 11}}[/tex]
Therefore , value of x is -11 .#Keep LearningPLEASE HELP!!!! 20 POINTSSSS!!!!!!!!!!

Which statement about the ordered pairs (2, -9) and (3,6) is true for the equation 5x - y/3 = 13?
A) (3, -6) is a solution to the equation.
B) Neither ordered pair is a solution.
C) (2, -9) is a solution to the equation.
D) Both ordered pairs are solutions.
Answer:
C) (2, -9) is a solution to the equation.
Step-by-step explanation:
To find if both or one point is the solution to the equation, substitute the x and y-values of both points into the equation to find which one makes a true and correct statement (the answer).
For (2, -9):
[tex]\sf5x - \frac{y}{3} = 13\\\\5(2) - \frac{-9}{3} = 13\\\\10-(-3)=13\\\\10+3=13\\\\ \boxed{13=13}\\\\\ \textsf{This is a true statement}\\\textsf{This means that (2, -9) is a solution to 5x - y/3 = 13}[/tex]
For (3, -6);
[tex]\sf5x - \frac{y}{3} = 13\\\\5(3) - \frac{-6}{3} = 13\\\\15-(-2)=13\\\\15+2=13\\\\ \boxed{17=13}\\\\\ \textsf{This is not a true statement}\\\textsf{This means that (3, -6) is not a solutions to 5x - y/3 = 13}[/tex]
Therefore, the correct answer is C

What is a circle?A circle is the locus of a point such that its distance from a fixed point (center) is always constant.
When a line intersects a circle in exactly one point the line is said to be tangent to the circle
Hence since Line CB touches circle A only at one point (point B), hence CB is a tangent.

A circle has a diameter of

What is the approximate
Circumference?
What is the approximate area?
Show ur work 40 points!!
Answer:
Circumference = 50.24 units
Area = 200.96 units²
Determining the area of the circle:
The formula of finding the area of the circle is π(r)² or π(d/2)².
(Where "r" represents the radius and "d" represents the diameter)
In this case, we are given the diameter. Thus, we will use the formula π(d/2)². Simply substitute the diameter in the formula to determine the area of the circle.
⇒ π(D/2)² = Area of circle
⇒ π(16/2)² = Area of circle
⇒ π(8)² = Area of circle
⇒ π × 64 = Area of circle
[Exact form of pie: 22/7; Approx form of pie: 3.14]
⇒ Area of circle ≈ 3.14 × 64
⇒ Area of circle ≈ 200.96 units²
Determining the circumference of the circle:
The formula of finding the circumference of a circle is 2πr or πd.
(Where "r" is radius and "d" is diameter)
In this case, we are given the diameter. Thus, we will use the formula πd. Simply substitute the diameter in the formula to determine the circumference of the circle.
⇒ πd = Circumference of circle
⇒ π(16) = Circumference of circle
[Exact form of pie: 22/7; Approx form of pie: 3.14]
⇒ (3.14)(16) ≈ Circumference of circle
⇒ 50.24 units ≈ Circumference of circle

Y=2x+11 5x+2y=-14
X=
y=
Answer:
x = -4, y = 3
Step-by-step explanation:
1. Substitute 2x + 11 for y:
5x + 2(2x + 11) = -14
2. Simplify:
2(2x) = 4x
4x + 5x = 9x, 2(11) = 22
so,
9x + 22 = -14
3. Isolate x:
9x + 22-22 = -14-22 = 9x -36
9x/9 = -36/9
x = -4
4. Plug in the value of x in to solve for y:
y = 2(-4) + 11
y = 3

Kelly's monthly profit for selling candles is represented by the function P (x) = 7.5x - 200, where x represents the number of candles sold. Complete each table
Profit is selling price minus cost price, we assumed that the number of candles sold is 100, then the profit is $550
Note: The question is not complete
Cost and Selling priceGiven Data
From the expression we can see the followingcost per candle = $7.5Number of candles sold for the month = xTotal cost of candles purchased for the month = $200We have the expression
P (x) = 7.5x - 200
Assuming the number of candles sold is x = 100
P (100) = 7.5*100 - 200
P (100) = 750 - 200
P (100) = $550

A vacant rectangular lot is being turned into a community vegetable garden with a uniform path around it. area of the lot is represented by 4x^2 40x - 44 where x is the width of the path in meters. Find the wisdom the path surrounding the garden.
By factorizing the expression, 4x² + 40x - 44, the width of the path (x) is calculated as: 11 meters.
How to Factorize an Expression?To factorize an expression, such as 4x² + 40x - 44, we need to determine the two factors that will give us -176 when multiplied, and also give us 40 when added.
To find the width of the path, x, we need to factorize 4x² + 40x - 44, using the two factors, 4 and -44.
4x² - 44x + 4x - 44
(4x² - 44x) + (4x - 44)
4x(x - 11) + 4(x - 11)
(x - 11)(4x + 4) = 0
x = 11 or x = -4/4 = -1
The value of the width of the path, x, cannot be negative. Therefore, the width of the path would be: 11 meters.
