Answer:

4+3√2y = 6

3√2y = -4+6

3√2y = 2

(3√2y)2 = (2)2

18y = 4

Add 4 to both sides

18y = 4

Divide both sides by 18

A possible solution is :

y = (2/9)

Answer:

y=2/9

Step-by-step explanation:

4+3√2y=6

3√2y+4=6

Step 1: Add -4 to both sides.

3√2y+4+−4=6+−4

3√2y=2........

The conversion of square feet to square yards can be represented by direct variation. Three square yards are

grandymaker [24]

<h3>The constant of variation is $\frac{1}{9}$ </h3><h3>The equation is $y=\frac{1}{9}x$ </h3>

<em><u>Solution:</u></em>

Given that,

The conversion of square feet to square yards can be represented by direct variation

Let y represent the number of square yards

Let x be the number of square feet

$y \propto x$

y = kx ------ eqn 1

Where, "k" is the constant of variation

Three square yards are equivalent to 27 square feet

Substitute, y = 3 and x = 27 in eqn 1

$3 = k \times 27\\\\k = \frac{3}{27}\\\\k = \frac{1}{9}$

Thus the constant of variation is $\frac{1}{9}$

<em><u>What is the equation representing the direct variation?</u></em>

Substitute k = 1/9 in eqn 1

$y = \frac{1}{9}x$

Thus the equation is found
