About 25 gallons of 20% mixture are needed to make the 80% mixture.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of gallons of 20% mixture needed, hence:
(20% of x) + (80% of y) = 65% of 100
0.2x + 0.8y = 65 (1)
Also:
x + y = 100 (2)
From both equations:
x = 25, y = 75
About 25 gallons of 20% mixture are needed to make the 80% mixture.

Answer:
3. Parallel lines have the same slope but different y-intercepts, so they never intercept each other.
Step-by-step explanation:
Don't you have a calculator? Just add those two numbers.
While adding 52 and 99 , It becomes 151
The answer is B because because 12x12=144 and 13x13=169 and nothing can multiply it’s self to become 156
Answer:
b) 3(9) + 4 = 36 + 4 = 40
c) 3(0) + 4 = 0 + 4 = 4
d) 3(-3) + 4 = -9 + 4 = -5
e) 3(8) + 4 = 24 + 4 = 28
