Answer:
x = - 5, y = - 9
Step-by-step explanation:
Given
x + 9i = - 5 - yi
For the 2 sides to be equal then the coefficients of like terms must be equal.
x = - 5 and 9 = - y ⇒ y = - 9
The answer would be 1,904 because a pound is 16 ounces so 8.5 times 14 (how many days are in two weeks) which is 119. Then 119 times 16 (how many ounces are in a pound) would be 1,904. hope i am helpful :D
