Step-by-step explanation:
Let
x-----> the final net price of a designer swimsuit
we know that
![x=\$85[1-\frac{25}{60}]](https://tex.z-dn.net/?f=x%3D%5C%2485%5B1-%5Cfrac%7B25%7D%7B60%7D%5D)
![x=\$85[\frac{35}{60}]](https://tex.z-dn.net/?f=x%3D%5C%2485%5B%5Cfrac%7B35%7D%7B60%7D%5D)
Let us say that:
x = age of brad
x + 2 = age of Alexandra
(x + 2) – 3 = age of Cecilia = x – 1
We are also given that:
x + x + 2 + x – 1 = 37
<span>
solving for x:</span>
3x + 1 = 37
3x = 36
x = 12 = age of brad
x + 2 = 14 = age of Alexandra
<span>x – 1 = 11 = age of cecilia</span>
Answer:

Step-by-step explanation:
Becuase 6 nickels add up to 30
the answer to your equation is 42 2/7
10x - 4y = 5 (if it requires shorten)
Step-by-step explanation:
x + y/5 - 1 = y - x
<=> (5x + y - 1.5)/5 = 5(y - x)/5
<=> 5x + y - 5 = 5y - 5x
<=> 5x + 5x + y - 5y = 5
<=> 10x - 4y = 5
