The triangle is x
The square is y
Left side
x + 3y is the weight
Right side
4x + y is the weight.
The weights are equal because the hanger is balanced.
Balance equation
x + 3y = 4x + y Subtract x from both sides
x-x + 3y = 4x-x + y Combine
3y = 3x + y Subtract y from both sides
3y - y = 3x + y - y Combine
2y = 3x
Answer
2y = 3x
Answer:
x +3y = 4x +y
Step-by-step explanation:
A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.
__
left sideThe left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...
x + 3y
right sideThe four triangles and 1 square on the right can have their total weight represented as ...
4x +y
balanceThe intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...
x +3y = 4x +y
_____
Additional comment
This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:
x +2y = 4x . . . . subtract y from both sides
2y = 3x . . . . . . . subtract x from both sides
y = (3/2)x . . . . . divide by the coefficient of y
This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.

How do you find the surface area of this?
Answers
Answer:
132
Step-by-step explanation:
No way you can find the whole area with one solution. So we have to go by each shape.
Let's start with the triangle on top, only one part of it. We know that half of the base is 3. We could go long and hard and use the pythagorean theorem and then repeat that 8 times. Instead, you can imagine moving the 2 triangles into a rectangle. Now you have a rectangle that is 3x4 inches. Repeat 4 times for each of the triangles. Then just the square which is 6x6. Add them and bam!
one step equation Y/1.8=80 what’s the answer?? ( with steps )
Answers
Answer:
5) Y = 144
Step-by-step explanation:
[tex]\frac{Y}{1.8} = 80[/tex]
Bring 1.8 from the numerator to the denominator and change the sign from divide to multiply. Also, the 1.8 switches sides so the equation looks like:
Y = 80*1.8
Y = 144
Hence, Y is equal to 144.

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-10y=-20
Answers
Slope-intercept form:
y = mx + b
First, you must get y alone by subtracting 2x on both sides of the equation and then dividing both sides by -10:
-10y = -2x - 20
y = -2/-10x - 20/-10
Simplify: y = 1/5x + 2
Answer: y = 1/5x + 2

Find the surface are of this figure
Answers
Answer:
If I am correct, I think the surface area is 448.
Step-by-step explanation:
First start by finding the area of all the sides
Front side. 12 x 10 = 120
2 triangle sides: 8 x 10 = 80, 80 x 2 = 160
Bottom side: 6 x 12 = 72
Back side: 8 x 12 = 96
Then add up the surface area
120 + 160 + 72 + 96 = 448
Btw I don't know if I am correct, but I think this is the way you find surface area.

The circumference of a circle is 125.6 millimeters. What is the circle's diameter?
Use 3.14 for .
Answers
Answer:
C = 2 pi r, so diameter is 40!
Step-by-step explanation
125.6 = 2 pi r
125.6 divided by 2 is 62.8.
Now its, 62.8 = pi times r
62.8/3.14 = 20.
r = 20
but this is the radius so the diameter is 2 times for than the radius. 20 x 2 = 40
