X + (7 - 3i) + (5 + 9i) + 13i = 10 - 5i
Subtract 13i from both sides
x + (7 -3i) + (5 + 9i) = 10 - 18i
Subtract (5 + 9i). MAKE SURE YOU SUBTRACT 9i TOO. In other words, distribute the negative and subtract 5 and 9i at the same time.
x + (7 - 3i) = 5 - 27i
Do the same with (7 - 3i). You'll be adding 3i since -(-3i) = 3i.
x = -2 - 24i
if you're talking about the whole number, 100.96. if you're referring to decimal place values; 96.70.
underline the digit that you round to
circle the digit to the right
five or more goes up
four or less stays the same
everything behind becomes a zero.
The answer would be the top left one, and the correct answer would be 17/8 or 2 1/8.
If you multiply 268 with 6, you get 1608 as your answer.
Is 12 I think so !! try it
