Answer:
A/2 - L = W
Step-by-step explanation:
A=2(L+W)
Divide each side by 2
A/2=2/2(L+W)
A/2=(L+W)
Subtract L
A/2 - L = L+W-L
A/2 - L = W
Answer:
A/2-L=W
Step-by-step explanation:
A/2=L+W
A/2-L=W

A line segment has a slope of -3/4. What is the slope of a line perpendicular to this line segment
Answer:
The slope of the line perpendicular to the line segment having slope [tex]-\dfrac{3}{4}[/tex] is [tex]\dfrac{4}{3}[/tex]
Step-by-step explanation:
Given the slope of the line perpendicular to the line segment is [tex]-\dfrac{3}{4}[/tex]
The expressions for the slope of line which are perpendicular to each other is given as [tex]m_{1} m_{2} =-1[/tex]
So the slope of the perpendicular line will be
[tex]m_{2} =-\frac{1}{m_{1} }[/tex]
[tex]m_{2} =-\frac{1}{-\frac{3}{4} }[/tex]
[tex]m_{2} =\dfrac{4}{3}[/tex]
Answer:
The slope of line perpendicular to the line segment that has a slope of [tex]\dfrac{-3}{4}[/tex] is [tex]\dfrac{4}{3}[/tex]
Step-by-step explanation:
Given,
The line segment has a slope of [tex]\dfrac{-3}{4}[/tex].
To find:
The slope of the line that is perpendicular to the given line segment.
Now,
Let suppose a line [tex]L_1[/tex] has a slope [tex]m_1[/tex] and line [tex]L_2[/tex] has a slope [tex]m_2[/tex].
Condition for perpendicularity:
If the product of the slopes of these lines equals -1, then the lines are perpendicular to each other.
Therefore, apply the above condition to our question.
So,
[tex]\begin{aligned}\dfrac{-3}{4}\times{\rm{slope\;of\;perpendicular\;line}}&=-1\\{\rm{slope\;of\;perpendicular\;line}}&=\dfrac{4}{3}\end{aligned}[/tex]
Find the slope of the line through each pair of points (20,-16),(19-16)
Answer:
Undefined slope.
Step-by-step explanation:
The formula should be y2 - y1 over x2 - x1
Points ( 20,-16 ) and ( 19, -16 )
So ( -16 - ( -16 ) ) over ( 19 - 20 )
0 over -1
The slope is 0. Undefined.
Answer:
Slope = 0
This line is not sloped. It moves flat relative to the x axis.
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
= (-16 - (-16)) / (19 - 20)
= (-16 + 16) / (-1)
= 0 / -1
= 0

[tex]\text{Let the number of puzzle solved by Child B is} x\text{.}[/tex]
[tex]\text{Then the average number of puzzle solved is}[/tex]
[tex]\frac{5x+x+(x+4)}{3}=13[/tex]
[tex]\frac{7x+4}{3}=13[/tex]
[tex]7x+4=39[/tex]
[tex]7x=35[/tex]
[tex]x=5[/tex]
[tex]\text{Therefore, the number of puzzles solved by child A is }5x=5\cdot5=25[/tex]
[tex]\color{blue}\text{A little tips here: You can check it by substituting your answer to the original equation.}[/tex]
Answer:
You are correct.
Step-by-step explanation:
[tex]13 \times 3 = 9[/tex]
Child B completed [tex] x [/tex]
Child A = [tex]5x[/tex]
Child C = [tex]x + 4[/tex]
[tex]x + 5x + x + 4 = 39[/tex]
[tex]7x = 35[/tex]
[tex]x = 5[/tex]
Child A = [tex]5 \times 5 = 25[/tex]

Amy spent $35 on a magazine and seven notepads. If the magazine costs $7, then how much was each notepad?
Hello :D
To work this out you need to do:
$35 - $7 = $28
$28/7 = $4
Each notebook costed $4
if 4 is added to greater number the sum is thrice the smaller number find the number
Sentence is not clear, but based on what i understood :
The following sum : "4 added to a greater number" can be written as follow. Let x be that greater number (x > 4) :
"4 + x"
Then this Sum's value, is thrice the smaller number : 3 × 4 = 12.
Finally, we need to solve this equation :
4 + x = 3 × 4
4 + x = 12
We subtract 4 on both sides of the equation :
4 + x - 4 = 12 - 4
x = 8
So this number x, is equal to 8.

Sarah has saved $150. She wants to double the amount she saves each month. As an incentive, Sarah’s grandma says if she saves that amount, she will give her an additional $50 each month. What are the recursive formula and first term for Sarah’s saving’s?
Answer:
A₁ = $150.
Step-by-step explanation:
We know that:
Sarah has saved $150 at the moment.
She wants to double the amount that she saves each month, so the next month she needs to save 2*$150 = $300
And if she saves the $300, then her grandma will give her another $50.
Then, if the previous month Sarah saved A, then the next month she will get the double of A plus $50, which is:
2*A + $50
Then the recursive relation is just:
Where Aₙ is the amount that she saves in the n-th month, and the first term of the sequence is the initial amount that she saved, so we have:
A₁ = $150.

What is the image of (0,6) after a dilation by a scale factor of 1/3 centered at the origin?
Answer:
(0,2)
Step-by-step explanation:
Since the point is being dilated about the origin, you can just multiply the x and y values of the point by the scale factor. 1/3 x 0 = 0, and 1/3 x 6 = 2.
Answer:
(0,2)
Step-by-step explanation:
Multiply each coordinate by the scale factor.

Write the equation of a line that is perpendicular to y=-2/7x + 9 and that passes through the point (4,-6)
Answer:
y = 3.5x - 20Step-by-step explanation:
The line perpendicular to the given has a negative reciprocal slope:
m = 7/2Use point-slope form to find the y-intercept and the equation:
y - y₁ = m(x - x₁), where (x₁, y₁) is the given pointy - (-6) = 7/2(x - 4)y = 7/2x - 14 - 6y = 7/2x - 20or
y = 3.5x - 20Are -3/5 and -0.4 equal

Are -3/5 and -0.4 equal ?[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Okay so, to solve this question we need to convert -3/5 to its decimal form.[tex] \large \sf - \frac{3}{5} = - 0.6 \\ [/tex]We can see that - 3/5 is equal to - 0.6 which is not equal to -0.4.So, - 3/5 & - 0.4 are not equal.Hey there!
Convert the fraction to decimals.
-3/5 = -0.6
-0.6 < -0.4
Hence, -3/5 is not equal to -0.4.

The first container of milk contains twice as much milk as the second container and the 3 gallons of milk from the first container, the first container has 4.5 times as much milk as the second. How many gallons of milk were in each container originally?
Answer:
There are [tex]4.58[/tex] gallons of milk in each container.
Step-by-step explanation:
Given:
[tex]1[/tex]st container has [tex]2x[/tex] gal.
[tex]2[/tex]nd container has [tex]x[/tex] gal.
To calculate the number of gallons
[tex]2x - 3 = x-2 + 4.5(x-2)[/tex]
[tex]2x - 3 = 5.5x - 11[/tex]
[tex]-3.5x = -8[/tex]
[tex]x = 2.29[/tex] gal.
[tex]2x = 4.58[/tex] gal.
Hence, there are [tex]4.58[/tex] gallons of milk in each container originally.
