Answer:

X = -9

Step-by-step explanation:

y = k X for some fixed number constant k.

-5 = k (15)

k = -5/15 = -1/3

So y = (-1/3)X

When y = 3 ---> 3 = (-1/3)X

X = -9

1. The product of five and a number is 15

dedylja [7]

Answer:

Step-by-step explanation:

(1) $5x = 15$

Dividing both sides by $5$ will give us the answer:

$x = 3$

(2) $x + 6 = 16$

Subtracting both sides by $6$ will give us the answer:

$x = 10$

(3) $\frac{27}{x} = 9$

First let's multiply both sides by $x$

$27 = 9x$

Now, let's divide both sides by $9$ to get our answer:

$x = 3$

(4) $6x = 72$

Dividing both sides by $6$ will give us the answer:

$x = 12$
