If the alcohol is absolute alcohol to make 1 gallon (4 quarts), then mix in 3 quarts water and 1 quart alcohol.

However, most of the time, alcohol comes in 96.5% alcohol, then we will define x=volume of alcohol in gal, then 1-x=volume of water, and solve following equation for x:
0.965x+(1-x)*0=0.25
x=0.25*0.965=0.259 gal
will need 0.259 gal of 96.5% alcohol and 0.741 gal. of water.

Which of the following equations is written in standard form?

Harlamova29_29 [7]

Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.

So, you can go through each of your options to see which ones work with those rules.

A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2<span> $\frac{1}{2}$ , menaing A is a fraction, which you can't have.

B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.

C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.

D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.

So, C and D are both written in Standard Form.
