The width of a rectangle is 3 cm less than twice its length. If the perimeter of the
rectangle is 18 cm, find its dimensions.
Answer:
length=4
Width=2×4-3=5
Step-by-step explanation:
Let length =X
Width =2x-3
Perimeter=18
2(length+width)=18
2(X+2x-3)=18
3x-3=9
3x=12
X=12/3
X=4
So length=4
Width=2×4-3=5
Answer:
[tex] \huge{ \boxed{ \bold{ \sf{Length \: = \: 4 \: cm}}}}[/tex]
[tex] \huge{ \boxed{ \bold{ \sf{Width = 5 \: cm}}}}[/tex]

☯ Question :
The width of a rectangle is 3 cm less than twice its length. If the perimeter of the rectangle is 18 cm, find its dimensions.☯ Step - by - step explanation :
✒ First, Let length of a rectangle be ' L '.
✑ Given :
Width of a rectangle = 3 cm less than twice its length ( i.e W = 2L - 3 )Perimeter of a rectangle ( P ) = 18 cm☞ Finding value of length of a rectangle :
[tex] \boxed{ \sf{Perimeter \: of \: a \: rectangle = 2(L + W)}}[/tex]
Plug the values and solve for L
➺ [tex] \sf{18 = 2(L+ 2L - 3)}[/tex]
➺ [tex] \sf{18 = 2(3L - 3)}[/tex] { Add : 2L and L )
➺ [tex] \sf{18 = 6L - 6}[/tex] { Distribute 2 through the parentheses )
➺ [tex] \sf{6L - 6 = 18}[/tex] { Swipe the sides of the equation }
➺ [tex] \sf{6L = 18 + 6}[/tex] { Move 6 to right hand side and change it's sign )
➺ [tex] \sf{6L = 24}[/tex] { Add the numbers : 18 and 6 }
➺ [tex] \sf{ \frac{6L}{6} = \frac{24}{6}} [/tex] { Divide both sides by 6 }
➺ [tex] \boxed{ \sf{length \: ( \: L\: ) \: = \: 4 \: cm}}[/tex]
☞ Now , Evaluating 2L - 3 when L = 4 cm in order to find the value of width of a rectangle : [tex] \sf{2l - 3}[/tex]
➺ [tex] \sf{2 \times 4 - 3}[/tex] { Plug the value of length }
➺ [tex] \sf{8 - 3}[/tex] { Multiply 2 by 4 }
➺ [tex] \boxed{ \sf{Width \: ( \: W \: ) \: = \: 5 \: cm}}[/tex]
Hence ,
Length of a rectangle ( L ) = 4 cmWidth of a rectangle ( W ) = 5 cmHope I helped!
Have a wonderful day! ツ

Find an equation of the sphere that passes through the point (6, -2, 3) and has center (-1, 2, 1). Find the curve in which the sphere intersects the yz-plane. Find the center and radius of the sphere
X^2 + y^2 + z^2 -8x + 2y +6z + 1 = 0
Answer:
A) x^2 + 2x+ y^2 - 4y + z^2 - 2z - 63 = 0
B) radius = 5
center = (4,-1,-3)
Step-by-step explanation:
[tex]x^2 + y^2 + z^2 - 8x + 2y + 6z + 1 = 0[/tex]
A ) Determine the curve in which the sphere intersects the yz-plane
determine the radius ( r ) = √((6-(-1))2+(-2-2)2+(3-1)2) = √69
next the equation of the sphere ( curve in which the sphere intersects the yz-plane )
x^2+2x+y^2-4y+z^2-2z-63 = 0
B) determine the center and radius of the sphere
X^2 + y^2 + z^2 -8x + 2y +6z + 1 = 0
(x-4)2+(y+1)2+(z+3)2 = 25 = 52
radius = 5
center = (4,-1,-3)

What is the image of -1,-4 after a reflection over the x axis
The image of the point after the reflection over x axis is P' ( -1 , 4 )
What is Reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.
The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
Given data ,
Let the point be represented as P
Now , the coordinates of the point P is P ( -1 , -4 )
The point P is reflected over the line x axis ,
So , when you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.
Substituting the values in the equation , we get
The image of the reflected point is P' ( -1 , - ( -4 ) )
The image of the reflected point is P' ( -1 , 4 )
Hence , the reflected point is P' ( -1 , 4 )

can't rely see it lol
Answer:
x = 60
Step-by-step explanation:
Answer:
x = 60°
Step-by-step explanation:
we know that triangles have 180 degrees so we can set up an equation:
86 + 34 + x = 180
now we subtract the sum of 86 and 34 from both sides to get a final answer:
x = 60
so lets plug our x value into the previous equation to check our answer:
86 + 34 + 60 = 180
when we add these numbers together, the equation checks out so we know our answer is correct.

Louis and Max are contestants in a jellybean-eating contest. Louis eats 18 jellybeans
in 30 seconds. Max eats 24 jellybeans in 40 seconds.
Answer: They ate at the same pace.
Step-by-step explanation: assuming you want to know who ate more faster you can do 18 / 30 and 24 / 4 to find out who ate more in 10 seconds each.
18 / 3 = 6 and 24 / 4 = 6. So they ate at the same speed / pace.

Carolyn Mills does maintenance work at a golf course. She worked these hours last season: April, 150; in each of the next four months, 200; September, 100. If she gets paid $10.50 an hour, what was her gross pay for the season?
Answer:
$11,025
Step-by-step explanation:
April: 150hrs
May-August: 200hrs x 4 = 800 hrs
September: 100 hrs
$10.50/hr pay rate
150+800+100 = $1,050
$1,050 x $10.50 = $11,025
*Gross pay is the amount of money made before tax
A fruit stand has to decide what to charge for their produce. They need $5.30 for 1 apple and 1 orange.
They also need $7.30 for 1 apple and 2 oranges. We put this information into a system of linear equations,
Answer:
The price of Apples is $3.30 and the price of Oranges is $2.
Step-by-step explanation:
So first treat the price of apples and the price of oranges as variables. Let's say that the price of an apple is X and the price of an orange is Y.
1 Apple and 1 Orange is $5.30, so the equation is 1X + 1Y = 5.30
1 Apple and 2 Oranges is 7.30 so the equation is 1X + 2Y = 7.30
Now, adjust one of the equations so you can know the price of one thing in relation to the price of the other.
1X + 1Y = 5.30 can become 1X = 5.30 - 1Y
Now substitute this into the other equation.
1X + 2Y = 7.30 becomes 5.30 - 1Y + 2Y = 7.30. Now, either combine the Y values or combine the price values.
5.30 + 1Y = 7.30
Y = $2
Now that you have the Y value, replace it in one of the equations.
1X + 2$ = 5.30
1X = 3.30

3а - 10 = a + 20
How do you do this help please it will mean a lot
Answer:
a=15
Step-by-step explanation:
2a-10=20
2a=30
a=15
can i have one brainliest plz
Answer:
a = 15
Step-by-step explanation:
I assumed you were trying to solve for A :)
3a - 10 = a + 20
1. Combine like terms (A's on side, numbers on the other).
3a - 10 = a + 20
-a -a
-----------------------
2a - 10 = 20
+10 +10
------------------------
2a = 30
Now that all of your like terms are combined, work to isolate A. The only way to do this is to divide by 2 on both sides of the equal sign.
[tex]\frac{2a}{2} = \frac{30}{2}[/tex]
This leaves you with a = 15, which is your answer if you are told to solve for A

A glass is
1
6
full. Then 95cm3 of orange juice is poured in.
The glass is now
4
5
full. What is the total volume of the glass?
Answer:
let x = the amount of orange juice in a full glass.
the glass is 1/6 full = 1/6 * x
add 95 cubic centimeters and the glass becomes 4/5 full.
equation for that is:
1/6 * x + 95 = 4/5 * x
subtract 1/6 * x from both sides of this equation to get:
95 = 4/5 * x - 1/6 * x
multiply 4/5 * 6/6 and multiply 1/6 * 5/5 and the equation becomes:
95 = 24/30 * x - 5/30 * x
combine like terms to get 95 = 19/30 * x
multiply both sides of the equation by 30/19 to get:
30/19 * 95 = 30/19 * 19/30 * x
simplify to get:
30/19 * 95 = x
solve for x to get x = 150.
the volume of the glass is 150 cubic centimeters.
1/6 * 150 = 25
4/5 * 150 = 120
the difference between 4/5 full and 1/6 full is 95 cubic centimeters.
solution is that the volume of the glass is 150 cubic centimeters.
