The sum will have an x-term sumtimes ... whenever
the x-terms alone don't add up to zero.
Examples:
-- Two linear expressions:
y + x
and
y + 2x
The sum of the x-terms alone is (x + 2x) = 3x .
So the sum of the expressions has an x-term.
(y + x) + (y + 2x) = 2y + 3x .
_______________________________
Two different linear expressions:
y + 3x
and
y - 3x
The sum of the x-terms alone is (3x - 3x) = zero.
So the sum of the expressions doesn't have an x-term.
(y + 3x) + (y - 3x) = 2y .

Multiply total number of gallons per day by number of quarts in one gallon
4 quarts= 1 gallon
= 12 gallons * 4 quarts in 1 gallon
= 48 quarts
ANSWER: He would use 48 quart pails of water per day to give his horse 12 gallons of water.
Hope this helps! :)
Answer:
25 degrees
Step-by-step explanation:
The sum of the 80 and 55 degree angles and the unknown angle x must be 180 degrees. Thus, x + 80 + 55 = 180, or x + 155 = 180, or x = 25.
x is 25 degrees.
This is based upon the "corresponding angles" principle. Lines AB and CD are parallel and are intersected by the longer diagonal line if we extend this line past the 80 and 55 degree angles.
