Answer: I can’t open it sorry
Step-by-step explanation:
we know that
a) 
gallon is equal to 
quarter of gallon
so
by proportion
gallons is equal to
quarter of gallon
b) liter is equal to 
quarter of gallon
by proportion
quarter of gallon is equal to
liters
therefore
the answer is the option
Answer:
Y = 40
Step-by-step explanation:
Change 1/2 to 2/4
2/4 y + 6 = 3/4y - 4
subtract 2/4y
6 = 1/4y -4
add 4
10 = 1/4y
multiply by 4 to get fraction to 1y or y
y = 40
The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.
<h3>What is an Algebra equation?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.
Let the number be x.
If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².
And if I square my number that is x² then subtract 20 from the result that is x² - 20.
Both the result are the same then we have
(x - 20)² = x² - 20
x² - 20x + 100 = x² - 20
-20x + 100 = -20
x = 6
My number is 6
