How many solutions does the following equation have?
-4(2 + 5) = -40 - 20

0

Step-by-step explanation:

I don't see any variables so simplify both sides.

-8 - 20 = -40 - 20

-28 = -60

is a false statement. No solutions.

16 km due west

Step-by-step explanation:

The bearing of the school p from school q is 16 km due west.

To find the bearing of school q from school p, we have to find the direction that the school q is with respect to school p.

Since p is directly west of q, then it implies that q must be directly east of p.

We now know the direction.

Since the distance from q to p is exactly the same as the distance from p to q, then, the distance from p to q is 16 km.

Hence, the bearing of q from p is 16 km due west.
