Step by step explanation::
three sides of a quadrilateral are the same length. q. the length of the forth side is 7 inches. the perimeter of the quadrilateral is 40 inches
Answer:
3q+7=40 I know im a year late but this is for whoever needs it this year Step-by-step explanation:using algebra the value of q is 11 inches Mark me as brainliestThe length of the equal sides of the given quadrilateral comes to be 11 inches.
What is a quadrilateral?A quadrilateral is a polygon with 4 sides.
Suppose the length of the three equal sides =x inch
Length of the fourth side =7 inches
So, the perimeter of the quadrilateral = x+x+x+7
The perimeter of the quadrilateral = 3x+7
Given that the perimeter of the quadrilateral = 40inches
3x+7=40
3x=33
x=11
So, the length of three equal sides = 11 inches
Therefore, the length of the equal sides of the given quadrilateral comes to be 11 inches.

Jamie buys a ring that is priced at $900. What is the sales price of the ring, if Jamie uses the coupon below?
A.$885
B.$15
C.$765
D.$135
Answer:
D= $135
Step-by-step explanation:
We have to use proportions in order to figure this out. We know that 15% is equal to 15/100.
work:
15/100=x/900.
We cross multiply so its 13,500/100. This is not the answer so we divide which equals to $135
83x - 6) = 6(4x + 8)
Answer:
[tex]x = \frac{54}{59}[/tex]
Step-by-step explanation:
I'm assuming you meant (83x - 6). Either way, the parentheses aren't needed there as there aren't any numbers outside of the parentheses on that side of the equation.
So:
Remember PEMDAS
P – Parentheses
E – Exponents
M – Multiplication /D – Division (whichever comes first from left to right)
A – Addition /S – Subtraction (whichever comes first from left to right)
Nothing needs to be distributed on the left side, so let's distribute the right side.
6(4x + 8)
6 * 4x = 24x
6 * 8 = 48
Now we have 24x + 48
83x - 6 = 24x + 48
Now, we must isolate the x so that in the end, we can get x =
83x - 6 = 24x + 48
+ 6 +6
83x = 24x + 54
-24x -24x
59x = 54
Now, we have isolated the x! Finally, we want x to = 1 so that it will be x = instead of 59x =.
[tex]\frac{59x}{59} = \frac{54}{59}[/tex]
Because 54/59 does not divide into a rational number or simplify any further, we can keep it as a fraction.
[tex]x = \frac{54}{59}[/tex]

A train is traveling at a constant speed and goes 7.5 kilometers in 6 minutes. At that rate:
How far does the train go in 1 minute?
how far does the train go in 100 minutes?
Answer:
1.25 km in 1 minute
125 km in 100 minutes
Step-by-step explanation:
Find its speed in km/min by dividing the km by number of minutes:
7.5/6
= 1.25
So, the train goes 1.25 km in 1 minute.
Using this speed, find how far it goes in 100 minutes, by multiplying the speed by 100:
1.25(100)
= 125
So, in 100 minutes, the train goes 125 km.
a. The distance travelled by the train in 1 minute, at a constant speed is 1.25 kilometers.
b. The distance travelled by the train in 100 minute, at a constant speed is 125 kilometers.
Given the following data:
Distance = 7.5 kilometersTime = 6 minutesTo find how far (distance) the train go in 1 minute, we would use direct proportion:
7.5 kilometers = 6 minutes
X kilometers = 1 minute
Cross-multiplying, we have:
[tex]6 \times X = 7.5\\\\X = \frac{7.5}{6}[/tex]
X = 1.25 kilometers.
b. To find how far (distance) the train go in 100 minute:
Since the train travels 1.25 kilometers in 1 minute, we would multiply that distance by 100.
[tex]D(100) = 1.25 \times 100\\D(100) = 125 \; kilometers[/tex]
Distance = 125 kilometers.

Answer:
x=3
6x-3 = 15
Step-by-step explanation:
The sides with the lines means they are the same length
The perimeter is
6x-3 + 6x -3 + 32 = 62
Combine like terms
12x+26=62
Subtract 26 from each side
12x+26-26 =62-26
12x =36
Divide by 12
12x/12 = 36/12
x = 3
The missing side length 6x-3 = 6*3 -3 = 18-3 = 15

I believe the answer is 90
Step-by-step explanation:
Answer:
90 degrees
Step-by-step explanation:
Calculate whether an angle is 90 degrees using the Pythagorean Theorem. This well-known theorem is often phrased as "A squared plus B squared equals C squared," which indicates that the sum of the squares of lengths of the adjacent sides of a right triangle is equal to the square of the length of the hypotenuse side.
Please help I'm trying to give up please help scams every time  fill in the two blanks please
Answer:
1st blank: 60 degrees
2nd blank: 120 degrees or -240 degrees
Step-by-step explanation:
1st blank: hexagons have a rotational symmetry of 60 degrees, and that's basically what the question was asking
2nd blank: If you rotate the hexagon around x once, it will map a point onto one of the points next to it depending on the direction.
In order to map F onto B, you need to either rotate it 120 degrees (2 rotations) counterclockwise or 240 degrees (4 rotations) clockwise.
A clockwise rotation is negative and a counterclockwise rotation is positive so that would be 120 degrees or -240 degrees.
solve each system of equations using substitution. x=y+1 x=3y+2
Answer:
x=1/2
y=-1/2
Step-by-step explanation:
x = y+1
x = 3y+2
Substitution means that you solve one equation for a variable by plugging it into the other equation. In this case, the first part is already done for you, and all you have to do is plugging in.
As you're given the value of the x in both equations, it does not matter which equation you plug into. You can plug either equation into one another.
For this, I will show you by plugging in the bottom equation for the top equation.
x = y+1
x = 3y+2
As we know x=3y+2, you must SUBSTITUTE that for the "x" in the top equation.
3y+2 = y+1
From there, you must solve it for the "y" value. In order to solve for the "y" value, you must get the "y" by itself onto one side.
So, subtract y from both sides.
(3y-y)+2 = (y-y)+1
Rewrite the equation.
2y+2 = 1
Remember, the goal is to get the "y" BY ITSELF.
There's a "+2" on the side of the y, so that has to be cancelled out. You can cancel it out by doing the OPPOSITE of adding, which is subtracting. So subtract both sides by 2.
2y+(2-2)=(1-2)
When subtracting a bigger number from a smaller number. The pattern is: Keep it, flip it, flip it.
Keep the 1.
Flip the - to a +
Flip the 2 into a -2.
So you get 1+(-2) which is -1. Now, rewrite the equation.
2y=-1
You want the y by itself. Right now, the y is being multiplied by 2, so you have to do the OPPOSITE, which is division. Divide both sides by 2.
y=-1/2
Now, use this value to plug into your ORIGINAL equations (you can pick either)
x = y+1 OR x = 3y+2
x= -1/2 + 1
x=1/2
(1/2, -1/2)
Solve for L.
P = 2L + 2W
L = 2/(P - W)
L = 2(W - 2P)
L = (P - 2W)/2
Answer:
L = (P - 2W)/2
Step-by-step explanation:
This is the formula for perimeter
P = 2L + 2W
Sustract 2W on both sides:
P-2W= 2L
Divide both sides by 2:
(P-2W)/2 = L
L= (P-2W)/2

In ABC the measure of the largest angle 32 less than 3 time the smallest angle the measure of the middle angle is 8 more than half the measure of the largest angle . What is the measure of the middle angle?
Answer: The measure of the middle angle = 52°
Step-by-step explanation:
Let x = Smallest angle.
largest angle = [tex]3x-32[/tex]
Middle angle= [tex]8+\dfrac12 (3x-32)[/tex]
Sum of all angles in a triangle is 180 degrees.
So, Smallest angle+ largest angle+ Middle angle = 180°
[tex]\Rightarrow\ x+8+\dfrac12 (3x-32)+3x-32=180\\\\\Rightarrow\ 4x-24+\dfrac{3x}{2}-16=180\\\\\Rightarrow\ \dfrac{2\times4x+3x}{2}-40=180\\\\\Rightarrow\ \dfrac{11x}{2}-40=180\\\\\Rightarrow\ \dfrac{11x}{2}=220\\\\\Rightarrow\ x=\dfrac{220\times2}{11}\\\\\Rightarrow\ x= 40[/tex]
Now , Middle angle= [tex]8+\dfrac12 (3(40)-32)=8+\dfrac12 (120-32)[/tex]
[tex]=8+\dfrac12 (88)\\\\=8+44\\\\=52[/tex]
Hence, the measure of the middle angle = 52°
