Step-by-step explanation:
supplementary means sum of two angles
with 180
Lets say the number = x
Six times a number is decreased by 9, the result is 3
6 times x is decreased by 9, the result is 3
(decreased means to subtract and results means equals)
6x - 9 = 3 (add 9 to each side)
<u> +9 +9</u>
6x = 3 + 9
6x = 12 (divide each side by 6)
6x/6 = 12/6
x = 2
The number is 2
Answer:
40 barrels
Step-by-step explanation:
Given that:
Let x = number of minutes
Old conveyor line :
Filling rate = 3 barrels per minute
Already filled = 10 barrels
Equation :
10 + 3x - - - (1)
NEW conveyor line:
Filling rate = 4 barrels per minute
Equation :
4x - - - (2)
Equate equation (1) and (2)
10 + 3x = 4x
10 = 4x - 3x
10 = x
Hence, in 10 minutes, each line will have filmed same number of barrels which is
4x = 4*10 = 40 barrels
10 + 3x = 10 + 3(10) = 40 barrels
