CAN SOMEONE PLEASE HELP ME WITH MY MATH CLASS PLEASEEE

-6

Step-by-step explanation: Here, we know that y varies directly with x.

When we have two sets of directly related coordinates, x₁ and y₁,

and x₂ and y₂, we can use the ratio below to find the missing value.

y₁/x₁ = y₂/x₂

Here, we know that y = -9 when x = 3.

So one set of coordinates will be .

We want to know the value of x when y = 18.

So the other coordinates will be .

So we have .

Now, we can solve for x using cross-products.

(-9)(x) is -9x and (3)(18) is 54.

So we have -9x = 54.

Now, we solve for x by dividing both sides of the equation by -9.

On the left, the -9's cancel and on the right, 54 divided by -9 is -6.

So -6 is equal to y.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
