Se escribe una equacion y se resolve.

Vamos a usar x para representar el peso de la piedra.

En en platillo que tiene la piedra, el peso total es: x + 1/9 + 2/3

En el otro platillo: 1/2 + 1/3

La balanza esta equilibrada por eso los pesos en los platillos son iguales.

x + 1/9 + 2/3 = 1/2 + 1/3

x + 2/18 + 12/18 = 9/18 + 6/18

x + 14/18 = 15/18

x = 1/18

Respuesta: La piedra pesa un octavo de kilogramo.

Translate each sentence into a formula
Bas_tet [7]
1) Perimeter=2length+2width
This is the formula for finding the perimeter of a rectangle

2) Density=mass/volume
The “Quotient” is the answer to a division problem (like how the “sum” is the answer to an addition problem) which is why we know to divide mass and volume

3) Force = mass*acceleration
The “product” is the answer to a multiplication problem which is why we know to multiply mass and acceleration

4) surface area = 6*L^2
The formula used to calculate the area of a square is L^2. The problem tells us that surface area is the sum of all the faces of a 3D shape. Because there are 6 sides on a cube, we multiply L^2 by 6.

Hope this helps!

Isaak is writing an explicit formula to represent the sequence.
gulaghasi [49]
In a geometric progression:
a, b, c, d...
The common ratio can be obtained using:
b/a = c/b = d/c
b/a = 112 / 64 = 1.75
c/b = 196 / 112 = 1.75
d/c = 343 / 196 = 1.75
The common ratio = 1.75
