12-5i + -3 + 4i
you will put them in brackets
(12-(5*i)) + (-3 +4*i)
is equal to 9-i
Hope this Help!
Distance = 30 mi
Speed = 45 mi/h
We know that Distance = Speed x Time OR Time = Distance/Speed
Time to go to the site: T = 30/45 = 0.66667 Hour. Multiply by 60 to get it in minutes: 0.66667 x 60 = 39.9999 ≈ 40 minutes
To come back he also spent the same time or 40 minutes
To and Fro = 80 minutes or 1 H 20 minutes
5*8=40
Answer: the total change in time was 40 seconds
Hope this helps:)
Answer:
x=150 degrees
Step-by-step explanation:
You know that the sum of the angles in a triangle is 180 degrees, so to find the missing angle in the triangle, subtract 180 from the sum of the other 2 angles: 180-(52+98)=180-150= 30 degrees.
You also know that the sum of supplementary angles is 180, and there are 2 supplementary angles. since we just found one of the angles, all we need to do is subtract 30 degrees from 180 degrees: 180-30= 150 degrees. (x is 150 degrees)
