2/3=x/6=9/y to find the value of y in this proportion you must divide 54 by
scZoUnD [109]

Answer:

You must divide 54 by 4

Step-by-step explanation:

we have

\frac{2}{3}=\frac{x}{6}=\frac{9}{y}

Step 1

Solve for x

\frac{2}{3}=\frac{x}{6}

3x=6*2\\x=12/3\\x=4

Step 2

Find the value of y

\frac{x}{6}=\frac{9}{y}

Substitute the value of x

\frac{4}{6}=\frac{9}{y}

4y=9*6\\y=54/4\\y= 13.5

therefore

You must divide 54 by 4

How do you find the x and y intercepts of 5x+4y=-20
irina1246 [14]

To find the y intercept, you cover x and it's coefficient and then divide -20 by 4 to get -5. To find the x intercept, you cover y and it's coefficient and divide 5 by -20 to get -4. So, x = -4 and y= -5

What is the y-value of the solution to the system of equations {3x+4y=42x−4y=6?
timofeeve [1]

The value of y for the system of equation is -1/2 .

<h3>What is a System of Equation ?</h3>

A system of equation is a set of equation that have common solution

The set of equation given is

3x+4y=4

2x−4y=6

To solve the system , Elimination method will be used

Add equation 1 and 2 to eliminate y

5x  = 10

x = 2

Substitute the value of x in equation 1 to determine y

3x +4y = 4

6 + 4y = 4

4y = -2

y = -1/2

Therefore the value of y for the system of equation is -1/2 .
