Answer:
1; all real numbers .
Step-by-step explanation:
340,000 : 5= 68,000
68,000 x 2 =136,000
so 2/5 of 340000 is 136,000
Slope = y1-y2/x1-x2 .. 5-3/-3--3 = math error (its parallel to y axis)
*Hint: In order to solve this equation and make it easier for you, you must use proportions and figure out how many quarts there is in 10% of antifreeze solution.
The reason you need to find it for 10% is because only 10% is needed in order for the solution to reach 40%.
12/30 = x/10
2/5 = x/10
4 = x
The answer would be 4 quarts.
