Answer:
d. - 15
Step-by-step explanation:
The equation for direct variation is
y = kx
We know y =3 when x = -9
3 = k(-9)
Divide by -9
3/-9 = -9k/-9
-1/3 = k
The equation is then
y = -1/3 x
We know y = 5
5 = -1/3 x
Multiply each side by -3
-3*5 = -3*-1/3x
-15 = x
Answer:
<em>~ 84 cm of the pop in the poster ~</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. Given the information, let us create a proportionality as such:</em>
7 = 1 ⇒ x - centimeters of the pop in the poster
x 12
<em>2. Now let us cross multiply, and solve through simple algebra for x:</em>
7 * 12 = x,
x =<em> 84 centimeters of the pop in the poster</em>
The answer is 9.2% because you multiply 125 by 9.2% which equals to 136.50
