A pair of shoes weighs more than an ounce
You would need 14 cases. You multiply 150 times 2 to get 300 which is 2 cases of soap per day and you multiply 7 days in a week by 2 and you let math magic happen
90 degrees. A right angle like this one is always 90 degrees.
Answer:
C.
Step-by-step explanation:
(x+yi)+(4+9i)=9-4i
x+yi+4+9i=9-4i
x+4+yi+9i=9-4i
Comparing the real and imaginary part we get:
x+4=9 OR y+9=-4(imaginary portion)
x=9-4 OR y=-4-9
x=5 OR y=-13
