Answer:
The amount of water to be added is ¹/₄ gallon
Step-by-step explanation:
Given;
amount of pure antifreeze at 100% = 1 gallon
let the amount of water to be added with 0% antifreeze = (x) gallon
then, the amount of mixture at 80% antifreeze = (x + 1) gallon
For conservation of mass, we will have the following equation;
(1 x 1) + (0)(x) = 0.8(x +1)
1 = 0.8x + 0.8
0.8x = 1 - 0.8
0.8x = 0.2
x = 0.2 / 0.8
x = ²/₈
x = ¹/₄ gallon
Therefore, the amount of water to be added is ¹/₄ gallon
First u locate the bottom part of the coordinate is the x axsis so look for the first number than u go up the y axsis then u look for the number so u plot

Answer:
The second equation B is correct
Step-by-step explanation:
N + Q = 32 and .5N + .25Q = 3.00
unlike the other equations this equation has the correct input for how much a quarter and nickel are worth relevant to the dollar amount rather than the coin amount.
