Answer: i think the answer is 320
Step-by-step explanation:
i say 320 because a square has 4 sides and there is 80 yards so all i did is multiply 80 x 4 = 320
Answer:
Step-by-step explanation:
[tex]d^2=x^2+x^2\\ \\ 2x^2=80^2\\ \\ 2x^2=6400\\ \\ x^2=3200\\ x=\sqrt{3200}\\ \\ P=4x\\ \\ P=4\sqrt{3200}yds\\ \\ P\approx 226.27yds[/tex]

You cannot take the square root of a negative number without involving imaginary numbers.
Answer and Explanation
__________________________________________________________
-10__________________________________________________________
The answer is -10 because...
You need to multiply 2 by "x," and to find out what "x" is, we need to add...
[tex]2+-12[/tex]
__________________________________________________________
And if we add [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.
__________________________________________________________
and now, if we add [tex]-20[/tex] by [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.

Answer:
[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex]
Step-by-step explanation:
We know that [tex]x[/tex] and [tex]y[/tex] are directly proportional. Therefore, using the given information, we can set up the following proportion:
[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]
Solving for [tex]y[/tex], we get:
[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]
[tex]12*y=6.5*4[/tex] (Cross-Products Property)
[tex]12y=26[/tex] (Simplify)
[tex]\frac{12y}{12} =\frac{26}{12}[/tex] (Divide both sides of the equation by [tex]12[/tex] to get rid of [tex]y[/tex]'s coefficient)
[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex] (Simplify)

Solve the system of equations by elimination. Show all work neatly on your work page. Checking your work is wise. :)
5x + 2y = 20
6x + 5y = 24
Answer:
(4,0)
Step-by-step explanation:
Let's solve your system by elimination.
5x+2y=20;6x+5y=24
Multiply the first equation by 5,and multiply the second equation by -2.
5(5x+2y=20)
−2(6x+5y=24)
Becomes:
25x+10y=100
−12x − 10y = −48
Add these equations to eliminate y:
13x = 52
Then solve13x=52for x:
13x=52
(Divide both sides by 13)
x=4
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
5x+2y=20
Substitute 4 for x in 5x + 2y = 20:
(5)(4)+2y=20
2y+20=20 (Simplify both sides of the equation)
2y+20+ −20 = 20 + −20 (Add -20 to both sides)
2y = 0
(Divide both sides by 2)
y=0

what is that area of the trapezoid
a)50in
b)108in
c)126in
b192in
Answer:
c) 126 inches of the answer
Answer:
C. 126 inches²
Step-by-step explanation:
To find the area of a trapezoid multiply the sum of the two bases (12 + 16) and the height divide by 2 (9 / 2) by each other
(12 + 16)9/2
Add 12 and 16 to get 28.
28(9/2)
Multiply 28 by 9 to get 252.
252/2
Divide 252 by 2 to get 126.
The area of the trapezoid is 126 inches².

How to construct the inscribed circle of a triangle?
Inscribed circle of a triangle is the largest circle, contained in the triangle.
Steps to construct the inscribed circle of a triangle-
Step 1-Bisect one of the angle of the triangle.Step 2-Now bisect the another angle of the triangle.Step 3-The crossing point of both the angle bisects is the in center of the triangle and center of the required circle.Step 4- Draw a perpendicular from this center to one of the side of the triangle.Step 5-Now draw a circle using the compass with the in center as a center of the and radius equal to the perpendicular from the in center to one of the side.Thus to construct the inscribed circle of a triangle the in-center is required. the option 3 is the correct option.

Answer:
3. 200
4. 9
Step-by-step explanation:
3. 300 divided by 1.5 is 200 which means 200 was the original price
4. 65 times .4 is 26 so 65 plus 26 is 91 and 100-91 is 9 so she had 9 left over

They subtracted 5 on both sides of the equation. They were suppose to add 5 on both sides of the equation for it to cancel out each other. If you need any further explanation, please ask me :)
Correct version:
5y + (-5) = 10
+5 +5 add 5 to both sides, 5's will cancel out on left side.
___________
5y 15
__ = __ divide 5 on both sides, 5's will cancel out on left side.
5 5
y = 3, final answer
Answer:
its the first part the (-5) -5 is supposed to be (-5) +5
Step-by-step explanation:
so the equation is 5y=15
then you divide 5y/5 is y so then you 15/5 is 3
so the answer is y=3

If the line containing the points (-2,10) and (7, 4) is dilated by a factor of 2, what is the
slope of the image?
ASAPPP NUMBER 2
===================================================
Explanation:
Let's compute the slope of the line through the two original points
m = (y2-y1)/(x2-x1)
m = (4-10)/(7-(-2))
m = (4-10)/(7+2)
m = -6/9
m = (-2*3)/(3*3)
m = -2/3
The slope is -2/3
-------------
Now apply the scale factor.
We'll multiply each coordinate of each point by 2
(-2,10) becomes (-4,20) after multiplying each coordinate by 2
(7,4) becomes (14,8) after multiplying each coordinate by 2
Let's find the slope of the line through (-4,20) and (14,8)
m = (y2-y1)/(x2-x1)
m = (8-20)/(14-(-4))
m = (8-20)/(14+4)
m = -12/18
m = (-2*6)/(3*6)
m = -2/3
We get the same slope. This isn't a coincidence. Dilating a set of points will preserve the slope of the line through those points.
If A and B are the two original points, and A' and B' are the dilated counterparts, then the slope of line AB is the same as the slope of line A'B'.
The scale factor doesn't affect the answer.

25+8x=5+12x whats the answer?
Answer:
x = 5 (see below)
Step-by-step explanation:
Combine like terms by subtracting on both sides:
25 + 8x = 5 + 12x
20 = 4x
Then divide:
20 = 4x
5 = x
Move the variable to the left side of the equation:
x = 5
Can anyone solve this for me?
Answer:
4x + 3 = 11
4x = 11 - 3
4x = 8
x = 8 ÷ 4
x = 2
3x - 5 = 7
3x = 7 + 5
3x = 12
x = 12 ÷ 3
x = 4
8x - 5 = -37
8x = -37 + 5
8x = -32
x = -32 ÷ 8
x = -4
7(x - 3) = 21
7x - 21 = 21
7x = 21 + 21
7x = 42
x = 42 ÷ 7
x = 6
Can someone tell me why is nobody helping me with my question I be POSTING 4 TIMES PLEASE YALL Help me please
Answer:
x = 4
y = 5
Step-by-step explanation:
4x = x + 12
^(subtract x from both sides)^
3x = 12
^(divide both sides by 3)^
x = 4
3y = 15
(divide both sides by 3)
y = 5
