<span>4x-17=23

We simplify the equation to the form, which is simple to understand
<span>4x-17=23

We move all terms containing x to the left and all other terms to the right.
<span>+4x=+23+17

We simplify left and right side of the equation.
<span>+4x=+40

We divide both sides of the equation by 4 to get x.
<span>x=10</span></span></span></span></span>

The following question find the value of the variables. If your answer is not an integer leave it in simplest radical form
Margarita [4]

Answer:

option 4

Step-by-step explanation:

using the sine/ cosine ratios in the right triangle and the exact values

cos30° = \frac{\sqrt{3} }{2} , sin30° = \frac{1}{2} , then

cos30° = \frac{adjacent}{hypotenuse} = \frac{x}{20\sqrt{3} } = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 20\sqrt{3} × \sqrt{3} = 20 × 3 = 60 ( divide both sides by 2 )

x = 30

and

sin30° = \frac{opposite}{hypotenuse} = \frac{y}{20\sqrt{3} } = \frac{1}{2} ( cross- multiply )

2y = 20\sqrt{3} ( divide both sides by 2 )

y = 10\sqrt{3}

If a is a negative number, then a(1/a) is equal to -1. If a is a negative number and b is a negative number, then product ab is
Firdavs [7]

Both claims are false. In fact, a and \frac{1}{a} are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that

a \cdot \dfrac{1}{a} = 1 \quad\forall a \in \mathbb{R}

So, it doesn't matter if a is positive or negative: the multiplication of one number and its inverse will always be 1: for example,

(-2) \cdot \dfrac{1}{-2} = \dfrac{-2}{-2} = 1

Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:

  • (+) \cdot (+) = (+)
  • (+) \cdot (-) = (-)
  • (-) \cdot (+) = (-)
  • (-) \cdot (-) = (+)

So, the multiplication of two negative numbers is a positive number.
