C (Y)
It's the only negative slope that goes to -3
Is there answer choices ?
Given:
5) The expressions are
![16x+24y+32](https://tex.z-dn.net/?f=16x%2B24y%2B32)
![8(2x+3y+4)](https://tex.z-dn.net/?f=8%282x%2B3y%2B4%29)
![4(4x+24y+8)](https://tex.z-dn.net/?f=4%284x%2B24y%2B8%29)
7) The expression is
![7(3-x)+15x](https://tex.z-dn.net/?f=7%283-x%29%2B15x)
To find:
5) Whether the given expressions are equivalent.
7) simplified form of given expression.
Solution:
5)
First expression is
![16x+24y+32](https://tex.z-dn.net/?f=16x%2B24y%2B32)
Second expression is
![8(2x+3y+4)](https://tex.z-dn.net/?f=8%282x%2B3y%2B4%29)
![=8(2x)+8(3y)+8(4)](https://tex.z-dn.net/?f=%3D8%282x%29%2B8%283y%29%2B8%284%29)
![=16x+24y+32](https://tex.z-dn.net/?f=%3D16x%2B24y%2B32)
Third expression is
![4(4x+24y+8)](https://tex.z-dn.net/?f=4%284x%2B24y%2B8%29)
![=4(4x)+4(24y)+4(8)](https://tex.z-dn.net/?f=%3D4%284x%29%2B4%2824y%29%2B4%288%29)
![=16x+96y+32](https://tex.z-dn.net/?f=%3D16x%2B96y%2B32)
Therefore, the simplified forms of given expressions are
respectively. It means only first and second expressions and equivalent.
7)
We have,
![7(3-x)+15x](https://tex.z-dn.net/?f=7%283-x%29%2B15x)
![=7(3)+7(-x)+15x](https://tex.z-dn.net/?f=%3D7%283%29%2B7%28-x%29%2B15x)
![=21-7x+15x](https://tex.z-dn.net/?f=%3D21-7x%2B15x)
![=21+8x](https://tex.z-dn.net/?f=%3D21%2B8x)
Therefore, the simplified form of given expression is
.
Remark
The easy way to do this is to change 5/8 to a decimal and worr y about changing it back to a fraction if you need to.
15 5/8 = 15.625 The easy way to find 5/8 is to use your calculator. 5 ÷ 8 = on most calculators.
You want 12 of these
1 leg is 15.625 inches long.
12 legs = x
1/12 = 15.625 / x Cross multiply
x = 12 * 15.625
x = 187.5 inches
Just how many feet is that? Divide by 12 to get the number of feet 187.5 / 12 =
15.625 feet.
Usually 2 by 4s are 8 or 12 feet long. For 8 feet you will need 2 of them and for 12 feet unfortunately you will need two as well.
Answer:
13, 16, 18
Step-by-step explanation:
Sabemos que podemos calcular el total de plumas amarillos, por medio de la media.
16 = (12 + 14 + 15 + 24 + x + y + z) / 7
16 * 7 = 12 + 14 + 15 + 24 + x + y + z
112 = 65 + x + y + z
x + y + z = 112-65
x + y + z = 47
sabemos que la mediana es el valor medio, y que ese 46 debe dividirse entre 3 valores porque son 3 cajas, entonces debemos buscar los números adecuados para el valor 15 esté en la mitad, es decir de cuarto.
Sin meter los valores nuevos, el ranking sería así:
12
14
15
24
el 15 esta de tercero, para que quede de cuarto, debe tener dos valores por debajo y un por arriba, así:
X
12
14
15
y
z
24
Por lo tanto, valores mayores a 15 serían por ejemplo y = 16 y z = 18:
16 + 18 = 34
x = 47-34 = 13
quedaría:
12
13
14
15
dieciséis
18 años
24
Si recalculamos la media:
m = (12 + 14 + 15 + 24 + 13 + 16 + 18) / 7 = 16
