Add Vectors in Different Ways Practice Test

A hiker walks $5$ units east and then $-2$ units east (i.e., $2$ units west). Treat these as vectors on the $x$-axis: $\mathbf{u}=\langle 5,0\rangle$ and $\mathbf{v}=\langle -2,0\rangle$. What are the components of $\mathbf{u}+\mathbf{v}$?

A hiker walks $5$ units east (vector $\mathbf{u}$) and then $3$ units north (vector $\mathbf{v}$). Using the end-to-end (head-to-tail) method, what is $\mathbf{u}+\mathbf{v}$ in component form (east = positive $x$, north = positive $y$)?
