Answer:
x = 3.5.
Step-by-step explanation:
This is an equilateral triangle ( as all angles = 60 degrees) so all 3 sides are of equal length.
Thus 2x - 3 = 4
2x = 7
x = 3.5.
Answer:
Rs 1000.97
Step-by-step explanation:
x = original price
new price = x (1.0909)(1.0833)(1.077) = 1274
x = Rs 1000.97
I think that this is right, but I assumed that the ceiling has the same dimensions as the wall you would need 4 gallons for 2 coats.
Work:
20x8= 160 (square feet for 1 wall)
160x5=800 (i assumed there are 4 walls and 1 ceiling)
800x2=1600 (you need 2 coats)
1600/400=4 (each gallon includes 400 square feet)
