Answer:
x = -15
m = -3
Step-by-step explanation:
3x + 6 = x - 24
subtract the x from both sides to make the unknown variable on only one side of the equation
2x + 6 = -24
subtract the 6 from both sides to focus on the x
2x = -30
now divide both sides by 2 to get the x by itself
x = -15
that's your answer
10 - 2m = 16
subtract the 10 from both sides to focus on the m
-2m = 6
now divide both sides by -2 to get the m by itself
m = -3
that's your answer

Find the value of 7w-8 given that -4w-5=3
Simplify your answer as much as possible.
7w - 8 =
Answer:
The value of 7w - 8 is -22
Step-by-step explanation:
Let us solve the question
∵ -4w - 5 = 3
→ Move -5 from the left side to the right side by adding both sides by 5
∴ -4w - 5 + 5 = 3 + 5
∴ -4w = 8
→ Divide both sides by -4
∵ [tex]\frac{-4w}{-4}[/tex] = [tex]\frac{8}{-4}[/tex]
∴ w = -2
→ Now let us find the value of the given expression
∵ The given expression is 7w - 8
→ Substitute w by -2 to gets its value
∴ 7w - 8 = 7(-2) - 8
∴ 7w - 8 = -14 - 8
∴ 7w - 8 = -22
∴ The value of 7w - 8 is -22

Which statement is true about the speeds of the two cars
someone convert 58.6...... into a fraction thank you!
Answer:
293/5
Step-by-step explanation:
Write 58.6 as
58.6/1
Multiply both numerator and denominator by 10 for every number after the decimal point
58.6 × 10
1 × 10= 586/10
Reducing the fraction gives
293/5
Whiskers the cat weighs 3 1/2 kg and Pilglio weighs 5 kg. How many times as heavy as pilglio is whiskers? How many times as heavy as whiskers is pilglio?
Given:
Whiskers the cat weighs [tex]3\dfrac{1}{2}[/tex] kg and Pilglio weighs 5 kg.
To find:
How many times as heavy as pilglio is whiskers?
How many times as heavy as whiskers is pilglio?
Solution:
We have,
Weight of cat (whiskers) = [tex]3\dfrac{1}{2}[/tex] kg
= [tex]\dfrac{3(2)+1}{2}[/tex] kg
= [tex]\dfrac{7}{2}[/tex] kg
= 3.5 kg
Weight of pilglio = 5 kg
Now,
[tex]\dfrac{Whiskers}{Pilglio}=\dfrac{3.5}{5}=0.7[/tex]
Therefore, whiskers is 0.7 times as heavy as pilglio.
[tex]\dfrac{Pilglio}{Whiskers}=\dfrac{5}{3.5}[/tex]
[tex]\dfrac{Pilglio}{Whiskers}=1.428571...[/tex]
[tex]\dfrac{Pilglio}{Whiskers}\approx 1.43[/tex]
Therefore, piglio is about 1.43 times as heavy as whiskers.

Write the equation of the ellipse graphed below.
I already asked this question but still no answer, sadly.
\Answer:
[tex]\displaystyle \frac{(x-7)^2}{4}+\frac{(y+2)^2}{36}=1[/tex]
Step-by-step explanation:
Equation of The Ellipse
Given the center (h,k) and the length of the major and minor axis, we can write the equation of the ellipse as follows:
[tex]\displaystyle \frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]
If the major axis is a, then the ellipse is horizontal, if the major axis is b, then the ellipse is vertical.
The ellipse shown in the figure is centered at (7,-2). The major axis is b and it can be found by measuring the distance from the center up or down to any vertex. We find b=6 and a=2.
Thus, the equation of the ellipse is:
[tex]\displaystyle \frac{(x-7)^2}{2^2}+\frac{(y+2)^2}{6^2}=1[/tex]
Operating:
[tex]\mathbf{\displaystyle \frac{(x-7)^2}{4}+\frac{(y+2)^2}{36}=1}[/tex]

Find the equation of the line described.

The line equation is y =
Answer:
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{19}{3}[/tex]
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 = 3x + 6 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] , thus
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c , substitute (4, 5) into the partial equation
5 = - [tex]\frac{4}{3}[/tex] + c ⇒ c = 5 + [tex]\frac{4}{3}[/tex] = [tex]\frac{19}{3}[/tex]
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{19}{3}[/tex] ← equation of perpendicular line
If θ is in standard position and -180° < θ <-90°, then θ terminates in Quadrant _____.
1) II
2) III
3) I
4) IV
Answer: Should be quadrant 3
Step-by-step explanation:
1 is everything in -360
2 is everything in -270
3 is everything in -180
4 is everything in -90
So basically it is less than -90 so it couldn’t be in quadrant 4 it would be before it so quadrant 3. Sorry if this is incorrect but it is to the best of my knowledge

A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the middle of the garden measures 30 feet. What is the distance around the perimeter of the garden? 120ft.
The perimeter of the rhombus is P = 120 feet
What is the perimeter of Rhombus?A Rhombus has four sides of the same length, its perimeter can be determined using the formula Perimeter = 4a, where "a" stands for the side's length.
When the two diagonals of a rhombus are known,
The perimeter = 2√p² + q²
where 'p' and 'q' are the diagonals.
Given data ,
Let the rhombus be represented as ABCD
Let the side length of the rhombus be AB = 30 feet
And , perimeter = 2√p² + q²
And , P = AB + BC + CD + AD
Due to the four triangles' similarity, we may conclude that AC is divided at O. So, we are aware that AO = 15 feet.
In ΔAOD,
(Perpendicular/hypotenuse) = sin 30°
or, 1/2 = 15/AD
otherwise, AD = 15 x 2 = 30 ft
So, AD equals 30 feet.
Given that all of a rhombus' sides are equal and all four of its triangles are the same, we have AB = BC = CD = AD = 30 feet.
On simplifying , we get
P = 4 ( 30 feet )
So , P = 120 feet
Hence , the perimeter is 120 feet

Answer:
We conclude that:
[tex]f\left(x\right)\cdot g\left(x\right)=x^3+13x^2+51x+63[/tex]
Step-by-step explanation:
Given

[tex]g(x)=x+3[/tex]
Determining f(x) · g(x)

Answer:
3. Markup $3.50 Retail Price $13.50
4.)Markup $10 Retail Price $50
Answer:
3. $ Markup = $3.50
Retail Price = $13.50
4. $ Markup = $10
Retail Price = $50
Step-by-step explanation:
Turn the % markups into decimals. For 3, you would turn the % markup into 0.35 and for 4 you would turn the % markup into 0.25.
Multiply the decimals by the price. Your result for the $ markup for 3 should be $3.50 and the result for 4 should be 10.
Now add the $ markup to the original price for 3 and 4.
10 + 3.50 = $13.50
40 + 10 = $50

What is the equation of the line that passes through the point (5,2) and has a
slope of -6
Answer: If the given slope is –6/5, the equation is
y –2 = –6/5(x -5)
The attachment shows the graph of this equation.
The point-slope form is y = –6x/5 + 8
Step-by-step explanation: The basic form for a point-slope equation is
y - b = m(x - a)
a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.
The slope, m, is given: -6/5 Substitute for m
Given coordinate points (5,2) substitute the x-value in place of a and the y-value in place of b
Rewrite the equation:
y - b = m(x - a) becomes
y - 2 = –6/5(x - 5)

12x+3=15x
show how u got the answer
Answer:
x = 1
Step-by-step explanation:
Given
12x + 3 = 15x ( subtract 12x from both sides )
3 = 3x ( divide both sides by 3 )
1 = x
Answer: x=1
Step-by-step explanation: So we're solving for x right but slight problem x is on both sides of the equation so we have to fix this. we can subtract 12x from both sides to get 12x-12x=0 and 15x-12x=3x so now we have 3x=3 to find x divide by 3 on both sided since 3/3=1 so 3x divided by 3 equals 1x or x and 3 divided by 3 is 1 so x=1
