Answer:

x = 2
(-5, 4, 6)

Step-by-step explanation:

1. Substitution can work for this.

2x +3(4x -5) = 13

14x = 28 . . . . . add 15

x = 2 . . . . . . . divide by 14

2. The equation z=6 eliminates all but the 1st and 3rd choices. Using that value in the first equation gives ...

x + y + 6 = 5

x + y = -1

Only the 3rd choice satisfies this equation.

(x, y, z) = (-5, 4, 6)

Before being simplified, the instructions for computing income tax in Country R were to add 2 percent of one’s annual income to

Vedmedyk [2.9K]

Answer:

Option C)

$50 + \dfrac{I}{40}$

Step-by-step explanation:

We are given the following in the question:

I is the annual income of a person in a country R

2 percent of one’s annual income =

$\dfrac{2}{100}\times I = 0.02I$

1 percent of one’s annual income =

$\dfrac{1}{100}\times I = 0.01I$

Average of 100 units of Country R’s currency and 1 percent of one’s annual income.

$=\dfrac{0.01I + 100}{2}$

Income tax =

2 percent of one’s annual income + Average of 100 units of Country R’s currency and 1 percent of one’s annual income.

$= 0.02I + \dfrac{100+0.01I}{2}\\\\=50 + \dfrac{0.04I + 0.01I}{2}\\\\=50 + \dfrac{0.05I}{2}\\\\= 50 + \dfrac{I}{40}$

Thus, income tax is given by

Option C)

$50 + \dfrac{I}{40}$

Ac=r+d for a solve equation for the indicated variable

konstantin123 [22]

$\boxed{a=\frac{r+d}{c}}$

<h2>Explanation:</h2>

Here we have the following expression:

$ac=r+d$

And the question asks for solving the equation for the variable $a$ . So we need to divide both sides of the equation by $c$ :

$ac=r+d \\ \\ \frac{ac}{c}=\frac{r+d}{c} \\ \\ \\ But: \\ \\ \frac{c}{c}=1 \\ \\ \\ So: \\ \\ \boxed{a=\frac{r+d}{c}}$
