4x – 5 + 2(x – 3) = 12x + 7
X=
Answer:
-3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
4x + 2x - 5 - 6 = 12x + 7
6x - 11 = 12x + 7
collect like terms
6x - 12x = 7 + 11
-6x = 18
-x = 3
x = -3

write the equation in slope y-intercept form: passing through the points (5, 7) and (-2, -3)
Answer:
y=10/7x-1/7
Step-by-step explanation:
m=(-3-7)/(-2-5)
m=-10/-7
m=10/7
y-y1=m(x-x1)
y-7=10/7(x-5)
y=10/7x-50/7+7
y=10/7x-50/7+49/7
y=10/7x-1/7

3. If the circumference of a circle is 44 m, find its area.
[tex]\pi[/tex]
Answer:
[tex] \huge\blue{ \mid{ \underline{ \overline{ \tt ♡ ANSWER : ♡ }} \mid}}[/tex]
Circumference of the circle = 44 m
Circumference Formula = 2πr
Let's take the radius as 'r' m.
Radius (r) =
[tex]2πr = 44 \\ 2 × 3.14 × r = 44 \\ r = 44/6.28 \\ r = 7 \: m.[/tex]
Area of the circle = πr²
[tex] = 3.14 × 7² \\ = 153.86 \: m ^{2} [/tex]
=> Area of the circle = 153.86 m² = 154 m² (approx.)
Phoebe has 72 roses that she is putting into 5 vases. If she puts the same number of roses in each vase, how many roses are left over?
Answer:
2 roses left over
Step-by-step explanation:
72/ 5 = 14.4
so we know for sure that we can put 14 roses on each vase but no mor than 14 on each vase Some will be left left over
14x5 = 70
72-70 = 2 (2 roses left over)
What is length of BW using what you know? DONT GIVE ME A LINK JUST ANSWE PLEASEE (will give brainlist)
Answer:
The length of BW is [tex]105\sqrt{2}[/tex], or about 148.49.
Step-by-step explanation:
For this problem, we will assume that the figure is a square. We will call the figure "Figure BOWL".
Because figure BOWL is a square, we know that the lengths of each sides of the square are equal, so the length of each side is 105.
Notice that the BW, OB, and WO make a triangle. We'll call it triangle BOW. Since figure BOWL is a square, we know that angle BOW is 90°, and so triangle BOW is a right triangle.
Since triangle BOW is a right triangle, we can solve for BW using the Pythagorean theorem, [tex]a^{2} + b^2 = c^2[/tex]. "a" and "b" are the legs of the triangle, while "c" is the hypotenuse of the triangle.
In triangle BOW, the legs are OB and WO, while the hypotenuse is BW.
Plug in the values for the equation and solve.
[tex]a^2 + b^2 = c^2[/tex]
[tex]OB^2 + WO^2 = BW^2[/tex]
[tex]105^2 + 105^2 = BW^2[/tex]
[tex]11,025 + 11,025 = BW^2[/tex]
[tex]22,050 = BW^2[/tex]
[tex]\sqrt{22,050} = BW[/tex]
We can either use the estimated value, or the exact simplified value of [tex]\sqrt{22,050}[/tex].
Here is the exact simplified value:
[tex]\sqrt{22,050} = \sqrt{25 * 882} = \sqrt{25 * 9 * 98} = \sqrt{25 * 9 * 49 * 2} = \sqrt{5^2 * 3^2 * 7^2 * 2} = (5 * 3 * 7)\sqrt{2} = 105\sqrt{2}[/tex]
BW = [tex]105\sqrt{2}[/tex]
For the estimated value, just use a calculator:
[tex]\sqrt{22,050}[/tex] ≈ 148.49
BW ≈ 148.49
Solve 2 (x+3) = x - 4

Find the surface area of a sphere with radius 5 using the formula SA=4pir2
Leave answer in terms of n
A. 75 pi units squared
B. 100 pi units squared
Answer:
B. 100 pi units squared
Step-by-step explanation:
Find the surface area of a sphere with radius 5 using the formula SA=4pir²
Leave answer in terms of π = pi
From the question
The formula for the Surface Area if a square = 4 × pi × r²
r = 5
Hence,
Surface Area of a Sphere = 4 × pi × 5²
= 100 pi units squared
Option B is the correct option
The total number of Karaks involved in flower cultivation is 1000. If the total population involved in the same is 2500, what percent of the total is the Karak population?
Answer:
Percentage of Karaks= 40%
Step-by-step explanation:
Giving the following information:
The total number of Karaks involved in flower cultivation is 1000.
Total population= 2,500
To calculate the percentage of Karaks, we need to use the following formula:
Percentage of Karaks= (1,000 / 2,500)*100
Percentage of Karaks= 40%
10. The perimeter of the rectangle below is 30 inches. Find the value of x.
5x
X-3
Using the perimeter formula of the rectangle, the value of x is 3 inches.
What exactly are rectangles?In the Euclidean plane, a rectangle is a quadrilateral with four right angles.A parallelogram with a right angle or an equiangular quadrilateral, where equiangular means that all of its angles are equal, are other ways to define it.A rectangle with four equal-length sides is a square.Rectangles are enclosed 2-D shapes with four sides, four corners, and four right angles.Equal and parallel opposite sides make up a rectangle.So, the value of x will be:
The formula for the perimeter of the rectangle: 2(l+b)Now, put the values in the formula and calculate x as follows:
2(l+b) = 302(5x+x-3) = 3010x + 2x -6 = 3012x - 6 = 3012x = 30+612x = 36x = 36/12x = 3Therefore, using the perimeter formula of the rectangle, the value of x is 3 inches.

The mean of a data set is 124. The mean absolute deviation is 38. What is the greatest possible number within the mean absolute deviation?
Answer:
Infinity
Step-by-step explanation:
The given parameters are;
The mean of the data, μ = 124
The mean absolute deviation = 38
The mean absolute deviation is given as follows;
[tex]Mean \ absolute \ deviation = \dfrac{\sum \left | X - \mu \right |}{N} = 38[/tex]
Where;
μ = Mean
X = Score
N = The number of scores
Therefore;
[tex]N \times 38 = \sum\limits_{i = 1}^N \left | X - \mu \right |} = \sum\limits_{i = 1}^N \left | X -124 \right |}[/tex]
When there are an infinite number of terms, N = ∞, the greatest possible number within the mean absolute deviation is therefore also infinite
[tex]\infty \times 38 = \sum\limits_{i = 1}^{\infty} \left | X - \mu \right |} = \infty[/tex]
[tex]Greatest \ possible \ value \ for \left | X - \mu \right |} = \infty[/tex]
