Answer:
1.25 gallons of alcohol
Step-by-step explanation:
Let x represent the amount of alcohol to add to the mix. Then the total amount of alcohol in the mix is ...
0.15×20 + x = 0.20×(20 +x)
3 +x = 4 + 0.2x . . . . simplify
0.8x = 1 . . . . . . . . . . add -3-0.2x
x = 1/0.8 = 1.25 . . . . divide by 0.8
1.25 gallons of alcohol should be added to make 21.25 gallons of 20% alcohol.
Answer:
multiplication property of equality
Step-by-step explanation:
Since we are multiplying by the same amount on each side, we are using the multiplication property of equality

Answer:
A student is sitting at a desk, getting ready for a math test.
Oh...no…I’m in big trouble. In all the days, why today do we have to have a pop quiz in math? I didn’t EVEN study! I just hate math! Ever since I started algebra, math has gotten harder and harder! Every time I look at an equation, the numbers get all mixed up and jumbled in my brain, and I try to remember the way to solve the problem. And by the time I find out how to solve that problem, HALF of the class is already DONE! But today might be a different day. Like they say, if you believe in yourself, anything is possible. Oh,no, Mr. Boyd is coming! (The teacher places the quiz in front of her/him.) (She/he looks at the quiz.) Oh, this doesn’t look half as bad. Ok, if two x plus fifty equals four x plus nine, then you bring the two over and… oh no! I forgot what you do next! (Sighs) ok, focus, focus. Breathe in, and breathe out.(Sighs) Ok, I got this.(Completes the rest of the quiz without a problem.) Finished! (Teacher comes by to collect his/her work.) Ok, I think I did good. I swear for the REST of my life I will never do a math problem again!

Hope you like it. I have hard time with Algebra.
