Largo= 3x+12 ("12 pies más (adición) que 3 veces (multiplicación) su ancho (x)")
En el problema incluyen el perímetro (la suma de todos los lados de una figura). En un rectángulo, los lados opuestos son congruentes, así que para calcular el valor de x, tenemos que sumar nuestras ecuaciones.
(3x+12)+(3x+12)+x+x=64
8x=64-24
x=40/8
x=5
Luego lo único que queda hacer es substituir el valor de x en cada ecuación para calcular los valores que te piden.

Answer: x=68, y=37
Step-by-step explanation:
The equation for the sum of two numbers is 105 would be x+y=105. You can say the larger number would be x and the smaller would be y. So, x=2y-6. then you plug that into the x in the first equation.
2y-6+y=105
3y-6=105
3y=111
y=37
Then you would plug in the y to one of the equations. I will do the second one but you can do either one.
x=2y-6
x=2*37-6
x=74-6
x=68

Sparrow has 92 coins, in the starting.
What is ratio?
Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Total number of coins in game = 210.
And the ratio of coins belongs to Ahab, Sparrow and Davy = 4 : 5 : 6
Let the multiplying factor in ration is x
The number of coins to Ahab = 4x
Number of coins belongs to Sparrow = 5x
And number of coins belong to Davy = 6x
Since, total number of coins = 210
4x + 5x + 6x = 210
15x = 210
x = 16
Number of coins that Sparrow has = 5 x = 5 (16) = 80
At the end Ahab and Davy wins 5 and 7 coins respectively
So at the starting coins that Sparrow has = 80 + 7 + 5 = 92
The required coins that Sparrow has at the beginning is 92.

at the end of game, sparrow has coins. since he loss 5+7=12 coins, then at the beginning he has 70+12=82 coins

Volume of a cylinder = A(base)*height
Volume of a cone = 1/3*A(base)*height
Because the base and height of the cylinder and cone are the same, we can write
Volume of the cone = 1/3*A(base)*height =1/3*Volume of the cylinder
Volume of the cone = 1/3*Volume of the cylinder, so
Volume of the cylinder=3*Volume of the cone =3*258.9=776.6 cm³
Volume of the cylinder= 776.6 cm³
Answer:
776.7 cm^3

The scale is the ratio of the model to the real thing.
So, in the scale 1:50, the model is 1, while the real thing is 50.
Now, just make a proportion:
the model : the real thing = the model dimension : the real thing dimension
1 : 50 = x : 8m
From here:
x = 8m * 1 / 50 = 0.16 m = 0.16 * 100 cm = 16 cm.
