We have two numbers that add to 42.... Call the larger number X and the smaller number Y X+Y = 42 We are told that Y is 12 less than X so Y = X-12 Substitute X-12 in place of Y in the original equation giving X + X -12 = 422X - 12 = 42Add 12 to both sides2X = 54Divide both sides by 2X = 27 Y = X-12 = 27 - 12 = 15 Our two numbers are 27, 15

Which expression is equivalent to x2 − x − 6 x2 + 2x − 15 ? A) x + 3 x + 5 B) x + 2 x + 5 C) x + 3 x − 3 D) x + 2 x − 3

Tema [17]

Answer:

Well, I am not sure which one is equivalent to another, but I have some information that should help you find your answer.

Step-by-step explanation:

The simplified expression to x2 − x − 6 x2 + 2x − 15 would be equal to −5 x 2 + x − 15.

The simplified expression to x + 3 x + 5 would be equal to 4x + 5.

The simplified expression to x + 2x + 5 would be equal to 3x + 5.

The simplified expression x + 3 x − 3 would be equal to 4x − 3.

The last simplified expression to x + 2 x − 3 would be equal to 3x − 3.

Hope this helps, I am really sorry if I didn't answer your question properly, or the way you asked!

What is the length of a 50-inch TV that has a width of 27 inches?

drek231 [11]

Answer:

42.08inches

Step-by-step explanation:

Given data

SIze of TV= 50 inch

Width= 27inches

Length= ??

Applying Pythagoras theorem

z^2= x^2+y^2

50^2= x^2+27^2

square root both sides

50^2= x^2+27^2

2500= x^2+ 729

2500-729=x^2

1771=x^2

x= √1771

x= 42.08

Hence the lenght is 42.08inches

Cuál es el resultado de |-15| x (-5)

notka56 [123]

Answer:

$\frac{15}{x^5}$

Step-by-step explanation:

$\left|-15\right|x^{-5}$

Step 1: Apply exponent rule: $\:a^{-b}=\frac{1}{a^b}$

$=\left|-15\right|\frac{1}{x^5}$

Step 2: Multiply fractions: $a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}$

$=\frac{1\cdot \left|-15\right|}{x^5}$

Step 3: Simplify

$=\frac{15}{x^5}$

The result is $=\frac{15}{x^5}$

<u>Spanish/Espanól</u>

Respuesta:

$\frac{15}{x^5}$

Explicación paso a paso:

$\left|-15\right|x^{-5}$

Paso 1: aplique la regla del exponente: $\:a^{-b}=\frac{1}{a^b}$

$=\left|-15\right|\frac{1}{x^5}$

Paso 2: multiplica fracciones: $a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}$

$=\frac{1\cdot \left|-15\right|}{x^5}$

Paso 3: simplifica

$=\frac{15}{x^5}$

El resultado es $=\frac{15}{x^5}$
