Answer:
5-46i
Step-by-step explanation:
first multiply your (10-4i)(4-5i) so that would be 20-66i when simplified. then add that to -15+20i so it would look like 20-66i+(-15+20i). then simplify and you should get 5-46i.
Answer:
The angles are vertical, and the value of x is 128 degrees
Step-by-step explanation:
You can tell vertical angles apart from adjacent by looking at their position. Adjacent angles are side by side, right next to each other. Vertical angles are directly across from each other, with their points touching.
Since the angle measures of vertical angles are equal, the value of x is 128
i hope this helps
Original volume = 2.5 million liters.
After evaporation, the remaining volume is 2 million liters, therefore
Evaporated volume = 2.5 - 2 = 0.5 million liters.
Percent of water evaporated = 100*(0.5/2.5) = 20%
Answer: 20%
D there is really no solution unless u get the value of x which I do not have so it can only be simplified into this equation above I hope this is correct and helpful
X+2y=1 well yoiu have ti take away the xs and the your have to do the same tjimng ti the ys
