![t = \frac{3}{20}](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7B3%7D%7B20%7D%20)
<h3>Step-by-step explaination:</h3>
![\frac{1}{3} t + \frac{4}{5} = \frac{3}{5} - t](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20t%20%2B%20%20%5Cfrac%7B4%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B3%7D%7B5%7D%20%20-%20t)
<h3>1. Substract 1/5 from both sides</h3>
![\frac{1}{3} t + \frac{4}{5} - \frac{4}{5} = \frac{3}{5} - t - \frac{4}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20t%20%2B%20%20%5Cfrac%7B4%7D%7B5%7D%20%20-%20%20%5Cfrac%7B4%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B3%7D%7B5%7D%20%20-%20t%20-%20%20%5Cfrac%7B4%7D%7B5%7D%20)
<h3>2. Simplify </h3>
![\frac{1}{3} t = - t - \frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20t%20%3D%20%20-%20t%20-%20%20%5Cfrac%7B1%7D%7B5%7D%20)
<h3 /><h3>3. Add t to both sides </h3>
![\frac{1}{3} t + t = - t - \frac{1}{5} + t](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20t%20%20%2B%20t%20%3D%20%20-%20t%20-%20%20%5Cfrac%7B1%7D%7B5%7D%20%20%2B%20t)
<h3>4. Simplify</h3>
![4t = - \frac{3}{5}](https://tex.z-dn.net/?f=4t%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B5%7D%20)
<h3 /><h3>5. Divide both sides by 4</h3>
![\frac{4t}{4} = \frac{ - \frac{3}{5} }{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4t%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B%20-%20%20%5Cfrac%7B3%7D%7B5%7D%20%7D%7B4%7D%20)
<h3 /><h3>6. Simplify</h3>
![t = - \frac{3}{2 0}](https://tex.z-dn.net/?f=t%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%200%7D%20)
<h3 /><h3>Solution : </h3>
= ![t = - \frac{3}{20}](https://tex.z-dn.net/?f=t%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B20%7D%20)
Answer:
9
Step-by-step explanation:
Multiply the cost by the tip percent
$125 * .15 = 18.75
Answer:
2.5 Pounds
Step-by-step explanation:
10 cubic centimeters of a 60% alcohol solution, would mean 10 x 60% = 6 cc is alcohol the other 4 cc is water.
To make a 90% solution, the water would be 10% of the solution.
If 4 cc is 10%, the total is 40 cc.
40 - 10 = 30 cc
30 cubic centimeters needs to be added.
