Answer:
x=10
Step-by-step explanation:
2(x-4)=12
2x-8=12
2x=20
x=10
Answer:
[tex]\huge{\boxed{\sf{10}}}[/tex]
Step-by-step explanation:
[tex]2(x - 4 ) = 12[/tex]
Distribute 2 through the parentheses
⇒[tex]2*x - 2*4 = 12\\[/tex]
⇒[tex]2x - 8 = 12\\[/tex]
Move 8 to right hand side and change its sign.
⇒[tex]2x=12+8[/tex]
Add the numbers: 12 and 8
⇒[tex]2x=20[/tex]
Divide both sides by 2
⇒[tex]\frac{2x}{2} = \frac{20}{2}[/tex]
⇒[tex]x = 10[/tex]
The value of x is 10.
Hope I helped!

Two times the sum of a number and 8 subtracted from the number equals 6. What is the number that makes this statement true?
Answer:
7
Step-by-step explanation:
let the no. be 'x'
By question,
2x-8=6
or, 2x =6+8
or,2x = 14
or,x = 7
therefore, the no. is 7.
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
maximum height reached by the rocket, to the nearest tenth of a foot.
y = -16x2 + 119x + 73
Answer:
294.3 ftStep-by-step explanation:
Given function
y = -16x^2 + 119x + 73This is quadratic function
It reaches the maximum value at vertex, which is calculated by the formula:
x = -b/2aSubstituting values
x = -119/2*(-16) = 3.71875y-value of same point is
y = -16*3.71875^2 + 119*3.71875 + 73 = 294.265625 ≈ 294.3 ftSo maximum height is 294.3 ft
The equation we have is:
[tex]y = { - 16x}^{2 } + 119x + 73[/tex]
This is equation of a parabola that opens down.
To find the maximum point or the maximum height, we need to find the vertex of the parabola.
First, let's define variables:
A will be the coefficient of the x squared.
b is the coefficient of the x and
C is the independent term:
[tex]a = - 16 \\ b = 119 \\ c = 73[/tex]
The vertex of will have the following x coordinate:
[tex]x = - \frac{b}{2a} [/tex]
Substituting the values of a and b:
[tex]x = - \frac{119}{2( - 16)} [/tex]
Solving the operations:
[tex]x = - \frac{119}{ - 32 } \\ x = 3.71875[/tex]
The next step is to substitute this x value into our equation to find the maximum height y:
[tex]y = { - 16x}^{2} + 119x + 73 \\ \\ substituting \: x = 3.71875 \\ \\ y = - 16(3.71875)^{2} + 119(3.71875) + 73[/tex]
Solving the operations:
[tex]y = - 16(13.8291) + 442.49555 + 73 \\ \\ y = 294.23[/tex]
Rounding to the nearest tenth (1 decimal place)
y=294.2
Answer: 294.2 feet.
HELP TRYNA GTSSS RN STRESSFUL DAYY
Answer:
y = 3x - 3
Step-by-step explanation:
y = mx + b
m = slope
slope = y2 - y1/x2 - x1
slope = 6 - 3/3 - 2
slope = 3/1
slope = 3
y = 3x + b
b = y-intercept
y-intercept is y when x = 0
rise over run
If slope = 3/1, then subtract 3 from y and 1 from x until x = 0
(2, 3) = 3/2
3 - 3/2 - 1 = 0/1 = (1, 0)
0 - 3/1- 1 = -3/0 = (0, -3)
x = 0
y-intercept = -3
y = 3x + - 3
negative + positive = negative
y = 3x - 3

2(m-n)=pz
Solve for m?
Answer:
m = [tex]\frac{pz+2n}{2}[/tex]
Step-by-step explanation:
Given
2(m - n) = pz ← distribute parenthesis on left side
2m - 2n = pz ( add 2n to both sides )
2m = pz + 2n ( divide both sides by 2 )
m = [tex]\frac{pz+2n}{2}[/tex]

Answer:
73.15 seconds or one min and 3.15 seconds
Step-by-step explanation:
x = amount of time it took Jonah to run the race
68.49 + 4.66 = x
x = 73.15 seconds
Line that is parallel to y=2x−4 and passes through the point (1,1).
Answer:
2x-6
Step-by-step explanation:
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 4 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 1) into the partial equation
1 = 2 + c ⇒ c = 1 - 2 = - 1
y = 2x - 1 ← equation of parallel line

How do I find the sum of the measures of the marked angles?
Answer:
The sum of the marked angles = Total angles on the 4 straight lines – Sum of the interior angles of the quadrilateral. Sum of interior angles of polygon of 4 sides = (4 – 2) *1800 =3600
Hence, sum of the marked angles = 4 * 180° – 360° = 720° – 360° = 360°
Step-by-step explanation:

The following triangle is isosceles. Find the measure of angle EFD.
Options:
28 degrees
44 degrees
20 degrees
36 degrees
Answer:
44°
Step-by-step explanation:
Because the triangle is isosceles, 4x+20 and 8x-4 would be equal
4x+20 = 8x - 4
4x + 20 - 4x = 8x - 4 - 4x
20 = 4x - 4
20 + 4 = 4x - 4 + 4
24 = 4x
x = 6
m∠EFD = 8x - 4
m∠EFD = 8(6) - 4
m∠EFD = 48 - 4
m∠EFD = 44°

WILL MARK YOU BRAINLIEST SHOW YOUR WORK PLZ!!! 6-7
Answer:
Number 6 is x=65 number 7 is x=-1
Step-by-step explanation:
I just did number 6 on another persons page but ill repeat it as best i can
You're going to set to X plus 2 = 3X -63 then you are going to subtract 2X from both sides which will leave you 2 equals X -63 and then you add 63 to both sides which will leave you x equals 65
Number 7
2X plus 20=6X plus 24
1st Subtract 2X from both sides which will leave you with 20 = 4X plus 24
2nd you're going to subtract 24 from both sides Which will leave you with negative 4 = 4X
Then you're going to divide both sides by 4 which will leave you with X equals negative one

Dontina is ordering uniforms for her employees. The company Dontina is ordering from charges $18 per uniform and a shipping fee of $7.
Based on this information, which function can be used to represent the relationship between the total cost, c, and the number of uniforms Dontina orders, n?
c = 18n + 7
c = 7n + 18
c=18n−7
c=7n−18
Answer:
c = 18n + 7
Step-by-step explanation:
Given the following data;
Total cost is represented by c
Number of uniforms ordered is represented by n
Shipping fee = $7
Cost per uniform = $18
The total cost is equal to the amount of money spent on ordering each uniform ($18) plus the shipping costs ($7).
Translating the word expression into an algebraic equation, we have;
c = 18n + 7
For example, if Dontina is ordering 10 uniforms for her employees.
n = 10
Substituting the value of n into the equation, we have;
c = 18(10) + 7
c = 180 + 7
c = $187
Therefore, the total cost incurred by Dontina in ordering 10 uniforms for her employees is $187.

Solve −2(2x + 5) − 3 = −3(x − 1)
Answer:
x= -16
Step-by-step explanation:
distribute -2
-2 * 2x =-4x
-2 * 5 = -10
-4x - 10 -3 = -3 (x-1)
distribute -3
-3 * x = -3x
-3 * -1 = 3
-4x - 10 -3 = -3x + 3
combine like terms
-4x -13 = -3x + 3
-4x + 3x = -x
3 + 13 = 16
-x = 16
divide by -1
x = -16
Answer:
x = -16
Step-by-step explanation:
-2(2x + 5) - 3 = -3(x - 1)
-4x - 10 - 3 = -3x + 3
-4x - 13 = -3x + 3
-x = 16
x = -16 <--- This is the answer

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of
silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.
Here is a system of equations that represent the constraints in the situation.
x + y = 4.25
16.90x + 4y = 36.35
1. What does the solution to the system represent?
2. Find the solution to the system of equations. Explain or show your reasoning.
Can someone fr help me on this like i want a answer like now
Answer:
Silk = x = 1.5 yards
Cotton = y = 2.75 yards
Step-by-step explanation:
x + y = 4.25
16.90x + 4y = 36.35
1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.
2.
x + y = 4.25 (1)
16.90x + 4y = 36.35 (2)
Multiply (1) by 4
4x + 4y = 17 (3)
16.90x + 4y = 36.35 (2)
Subtract (3) from (2)
16.90x - 4x = 36.35 - 17
12.90x = 19.35
Divide both sides by 12.90
x = 19.35 / 12.90
= 1.5
x = 1.5 yards
Substitute x = 1.5 yards into (1)
x + y = 4.25
1.5 + y = 4.25
y = 4.25 - 1.5
= 2.75
y = 2.75 yards
Silk = x = 1.5 yards
Cotton = y = 2.75 yards
