What is the value of x in the diagram below? If necessary, round your answer
dexar [7]

Answer:

\text{C. }7.2

Step-by-step explanation:

In the figure, all three triangles are similar. By definition, the corresponding sides of similar polygons must be in a constant proportion. Therefore, we can set up the following proportion to solve for x by dividing corresponding sides:

\frac{x}{12}=\frac{12}{20},\\20x=144,\\x=\frac{144}{20}=\boxed{\text{C. }7.2}

The solution to a system of linear equations is (-3,-3) Which system of linear equations has this point as its solution? x -5y=-
Ann [662]

Answer:

x-5y=12 and 3x+2y=-15

Step-by-step explanation:

The first system is

x-5y=-12 and 3x+2y=-15

We substitute x=-3 and y=-3

-3-5*-3=12\ne-12 and 3*-3+2*-3=-15

Both equations are not satisfied

The next system is

x-5y=12 and 3x+2y=-15

We substitute x=-3 and y=-3

-3-5*-3=12 and 3*-3+2*-3=-15\ne15

Both equations are satisfied

The next system is

x-5y=-12 and 3x+2y=15

We substitute x=-3 and y=-3

-3-5*-3=12\ne12 and 3*-3+2*-3=-15

Both equations are not satisfied

The next system is

x-5y=12 and 3x+2y=15

We substitute x=-3 and y=-3

-3-5*-3=12\ne-12 and 3*-3+2*-3=-15

Both equations are  not satisfied
