Answer:
-2 - 24i
Step-by-step explanation:
a + bi + (7 - 3i) + (5 + 9i) + 13i = 10 - 5i
a + bi + <u>7 + 5</u> - 3i + 9i + 13i = 10 - 5i
a + bi + 12 + 19i = 10 - 5i
a + bi = 10 - 5i - 12 - 9i
a + bi = 10 - 12 - 5i - 9i
a + bi = -2 - 24i
approximately 2/3 of all students are not wearing braces because 165 (the difference of 250-85) /250 is 0.66
If you try to solve for x it is not able to be solved because the variable must be located in between the inequality signs, but if i simplified your problem then it would be: x is greater than or equal to -2.
I really hoped this helped. Good luck.
Answer:
2A / r^2 = pi
Step-by-step explanation:
A = 1/2 pi r^2
Multiply by 2
2A = pi r^2
Divide by r^2
2A / r^2 = pi r^2/r^2
2A / r^2 = pi
