<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

devi and her brother had the same amount of money. after devi spent 2/5 of her money and her brother spent 3/10 of his money, th
krok68 [10]
To answer this question you have to create a system of equations. The first equation will be that Devi's money (x) equals her brother's money (y), or x = y. The next equation would be that (3/5)x + (7/10)y = 78. You than can substitute x in for y because x = y. The equation would know be (3/5)x + (7/10)x = 78. You then combine the like terms to create an equation of (13/10)x = 78. Then, multiply both sides by 10 / 13 in order to isolate x. This will create the equation x = 60. This means that Devi and her brother each had 60 dollars. You then find out how much they spent and add it together. You can do so with the equation (2/5)x + (3/10)y = z, with z being total money spent. You substitute 60 in for x and for y then solve. When you solve you see that 24 + 18 = z, or that z equals 42. In other words, they spent 42 dollars altogether.

blsea [12.9K]
Let x represent the amount of lawn mowers that were manufactured

The company has to pay $34,816 before they even make any lawn mowers plus $388 per lawn mower.

((34816+388x)/x)=660
34816+388x=660x
34816=272x
X=128

Therefore, there were 128 lawn mowers manufactured
