Answer:

v=99

Step-by-step explanation:

We have been given that that v varies directly as g.

We can represent this information in an equation as:

v=kg

First of all, we will find constant of variation (k) by substituting v=36 and g=4 in our given equation.

36=k\cdot 4

\frac{36}{4}=\frac{k\cdot 4}{4}

9=k

So our equation would be v=9g.

Now, we will substitute  g=11 in the given equation:

v=9\times 11

v=99

Therefore, the value of v is 99.

For a variable to vary directly to another is telling you to set up a proportion

v/g = v/g

36/4 = v/11

4v = 396

v = 99

Solve with using elimination <br>3х + 5y = 54<br>6х +4y = 72​
pickupchik [31]

Answer:

<u>y = 6 x=8</u>

Step-by-step explanation:

(3х + 5y = 54)-2 times by -2

-6х + -10y = -108 now combine the equations

6х + 4y = 72

-6y = -36 now divide

y = 6

Plug 6 in 6х +4 * 6 = 72
