What is the constant of proportionality for 6,47.94?
Maurinko [17]

\boxed{k=7.99}

<h2>Explanation:</h2>

In this exercise, we have the following point:

(6,47.94)

Let's assume that y varies directly as x, so this implies we can writ y as the product of x and some non-zero real constant k. In a mathematical language:

y=kx

As you can see, this is the equation of a line whose slope is k and passes through the origin. Therefore, the slope of the line is the constant of proportionality we are looking for:

Solving \ the \ equation \ for \ k: \\ \\ k\frac{y}{x} \\ \\ Where: \\ \\ x=6 \\ y=47.94 \\ \\ k=\frac{47.94}{6} \\ \\ \therefore \boxed{k=7.99}

Solve for x. Show work<br><br><br> 10-1/2x = 6 + 3x
Vikki [24]
<h3>Answer:</h3>

x =  \frac{8}{7}

<h3>Step-by-step explanation:</h3>

10 -  \frac{1}{2} x = 6 + 3x

20 - x = 12 + 6x

20 - x - 6x = 12 + 6x - 6x

20 - x - 6x = 12

- x - 6x = 12 - 20

- 7x = 12 - 20

- 7x =  - 8

x =  \frac{8}{7}
