Answer: 24
Step-by-step explanation:
Follow PEMDAS. Parentheses: 16+a, which is 18. There are no exponents so move on to multiplication. 6b. B is equal to 3, and 6x3 is 18. Next, division. 18/3 is 6. Now do addition so add together 18+6 which is 24.
Speed = distance/time
Speed = 90 meters/45 seconds
Simplify the above answer
Speed = 2 meters/second
You can double-check this: You walk 2 meters per second, so multiply 2 by 45 (that is how many seconds), and you get 90.

Answer:
Step-by-step explanation:
One is asked to find the distance between two points on a coordinate plane. The easiest way to do so is to use the distance formula, this formula is the following:
Where (
) and (
) are the points which one needs to find the distance between. In this case, these points are as follows:
Substitute these points into the formula and solve for the distance between these points,
Simplify,
