Nostrana [21]

Answer:

The number is 135.

Step-by-step explanation:

1) Form an equation

Three is subtracted from a number

⇒ $x-3$ (where x is "the number")

The difference is divided by 11

⇒ $\displaystyle \frac{x-3}{11}$

The result is 12

⇒ $\displaystyle \frac{x-3}{11}=12$

2) Solve the equation

$\displaystyle \frac{x-3}{11}=12$

Multiply both sides by 11

$\displaystyle \frac{x-3}{11}*11=12*11\\\\x-3=132$

Add 3 to both sides

$x-3+3=132+3\\x=135$

Therefore, the number is 135.

I hope this helps!

Which is the best description of the equivalency of the two expressions? Expression 1 Expression 2 5 x squared minus 2 x minus 4

lina2011 [118]

Answer:

The correct option is (D).

Step-by-step explanation:

The two expressions are:

$\text{Exp}_{1}=5x^{2}-2x-4+6x+3\\\\\text{Exp}_{2}=6x^{2}-6x+6-x^{2}+10x-7$

On simplifying both the expressions we get:

$\text{Exp}_{1}=5x^{2}+4x-1\\\\\text{Exp}_{2}=5x^{2}+4x-1$

Compute the value of both expressions for x = 2 as follows:

$\text{Exp}_{1}=5(2)^{2}+4(2)-1=27\\\\\text{Exp}_{2}=5(2)^{2}+4(2)-1=27$

The value of both expressions are same for x = 2.

Thus, the correct option is:

"They are equivalent because when x = 2, the two expressions have the same value."
