This is a fraction equal to
7 yards ÷ 4 dresses
We want a unit rate where
<span>1 is in the denominator, </span>
so we divide top and bottom by 4.
7÷4= 1.75
_
4÷4=1.
Therefore, Kate used 1.75 yards per one dress (1.75 yds. p/ d)
Hope I helped! :)
Hey!
To solve this equation, we'd first have to apply the distributing rule to this equation.
<em>Original Equation :</em>

<em>New Equation {Changed by Applying the Distribution Rule} :</em>

· 3a · 2 +

And now we simplify.
<em>Old Equation :</em>

· 3a · 2 +

<em>New Equation {Old Equation Simplified} :</em>

- 12a + 4
<em>So, the equation

simplified is</em>
- 12a + 4.Hope this helps!

Step-by-step explanation:
the amplitude is the height of the wave.
like with sound - the further away you are, the lower the volume of the sound (as the sound volume is the indicator of the amplitude of a sound wave, or the brightness of a light is the indicator of the amplitude of a light wave).
the same for any other type of wave (like the seismic wave of an earthquake).
so, the larger the distance, normally the smaller the amplitude.
