Shkiper50 [21]

Answer:

30/54

Step-by-step explanation:

1st make and equation so 5/9=x/54

now cross-multiply.

5/9=x/54

(5)*(54)=x*(9)

270=9x

you can flip the equation.

9x=270 (next divide both sides by 9)

x=30

so 30/54=5/9

hope this helps :)

1Find an equation of the line perpendicular to the graph of yx + 5 that has a y-4intercept of (0, -3). Write your equation in sl
lianna [129]

Given data:

The given equation of line is y=x/4+5.

The given y-intercept is (0,c)=(0,-3).

The standard equation of line is,

y=mx+c

Compare the given equation with the above expression.

m=1/4

The expression for the slope which is perpendicular to the given line.

\begin{gathered} m^{\prime}\times m=-1 \\ m^{\prime}(\frac{1}{4})=-1 \\ m^{\prime}=-4 \end{gathered}

The equation of the line which is perpendicular to the given line is,

\begin{gathered} y=m^{\prime}x+c \\ =-4x-3 \end{gathered}

Thus, the line which is perpendicular to the given line is y=-4x-3.

Gwent pour 256 milliliters of water in to Ravi Henry pours 189 milliters of water in to Ravis .Ravis now contains 800 Milliters
Contact [7]

Answer:

Ravi had 355ml water to begin with.

Step-by-step explanation:

Given that,

amount of water that Gwent pour in Ravi = 256 ml

amount of water that Henry pour in Ravi = 189 ml

amount of water after each have poured = 800 ml

suppose amount of water ravi had before both poured water in it = x

Equation

256 + 189 + x = 800

445 + x = 800

x = 355ml

Initially ravi had 335ml of water.
