Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
Answer:
Option (1).
Step-by-step explanation:
In the figure attached,
Houses of three friends Jo, Boris and Carrie are located at the vertices of a triangle.
They want to meet at a place which equidistant from these vertices.
A point in a triangle which is equidistant from the vertices is its Circumcenter.
A circumcenter of a triangle is a point of intersection of perpendicular bisectors of its sides.
Therefore, the next step to find the meeting place should be,
Option (1). They should find the midpoint of the segments which connect their houses.
Answer:
Option C.
Step-by-step explanation:
In this excercise we have to rest the altitude where they hiked on the second place, to the one were they departed from, in order to know how much they hiked.
So we do:
.
The correct option is option C.
I think it is c not sure though maybe double check.
