Answer:
Y = (16 - 3x)/5
Step-by-step explanation:
3x + 5y = 16
subtract 3x from both sides:
16-3x = 5y
divide both sides by 5:
(16 - 3x) / 5 = y

Okay, here we have this:
Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:
Solving for x:
Finally we obtain that 87.5mL of water should be used for 250g of plaster.
Answer:
find k by putting -3 where there is x than -6 on g(x)
Step-by-step explanation:
g(x)=3k-2x²
-6=3k-2(-3)²
-6=3k-18
-6+18=3k
12=3k
12÷3=3k÷3
4=k

Answer:
see explanation
Step-by-step explanation:
Given
2cosΘ - = 0 ( add to both sides )
2cosΘ = ( divide both sides by 2 )
cosΘ =
Since cosΘ > 0 then Θ is in first and fourth quadrants, hence
Θ = ( ) =
OR
Θ = 2π - =
solutions are Θ = ,
