Answer:
Step-by-step explanation:
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
2x + 3y = 45
x + y = 10......y = 10 - x
2x + 3(10 - x) = 45
2x + 30 - 3x = 45
-x + 30 = 45
-x = 45 - 30
-x = 15
x = -15 <====
and y = 25
Answer:
10.5 gallons
Step-by-step explanation:
48000 cm3 = 48 litres (1 litre = 1000 cm3)
Therefore if 1 litre = 1.75 pints then 48 litres = 48 x 1.75 = 84 pints.
Finally if 8 pints = 1 gallon
then 84 pints = (84 x 1) / 8 = 10.5 gallons
Answer:
Step-by-step explanation:
We have to use the slope formula: m = slope
(x1, y1) = coordinates of the first point in the line
(x2, y2) = coordinates of the second point in the line
Here, we'll plug into our given points to give; 
Solving this, we get, 
, but we're not done, as this fraction can be reduced.
Diving both sides of the fraction by 2, we get our final answer of .
