Answer:

C. 5

Step-by-step explanation:

∆LMN kid an isosceles triangles because it has two base triangles that are equal to each other. Therefore, the sides opposite the base triangles would also be equal to each other.

Thus:

3x = x + 10

Solve for x. Subtract x from each side

3x - x = 10

2x = 10

Divide both sides by 2

x = 5

Answer:

a = jd

Step-by-step explanation:

We want to solve for a given that a/d = j

To do so we want to isolate a (get a by itself )

We can do this by using inverse operations.

We would want to get rid of the d

A is being divided by d.

The inverse of division is multiplication so to get rid of the d we multiply a/d by d but whatever we do to one side we must do to the other so we multiply both sides by d

a/d * d = a

j * d = jd

we are then left with a = jd

And we are done!
