Answer:
9+11i
Step-by-step explanation:
12-3=9
4i-(-7i)=11
The answer to this equation is x=5.
The answer is g = 6w.
since the number of grey pigeons is 6 times the white pigeons, it means the white pigeons are being multiplied to find the number of grey pigeons
X^2+ (y+8)^2 = 81.....this is C.
X^2 + y^2 + 16y +64=81 so x^2 + y^2 + 16y = 17.....this is D.
So I’d say C and D are correct
The three items cost altogether is : 111.32 + 28.75 + 73.21 = 213.28
So, he must work 213.28 : 8.75 = 24.3748571429...
Since if he works 24 hours, he wouldn't have enough money to buy the 3 items, so he must work 24 + 1 = 25 hours.
Recheck : 25 x 8.75 = 218.75 ( > 213.28)
