Answer:
-42
Step-by-step explanation:
Since she is handing them equally to her four nieces, then she has to do 10.50 x 4
= 42 since they are asking how much checks were cashed, the answer will be negative so therefore the answer is $-42
6-11i
(2 + 7i) - (6 + 8i) + (10 - 10i)
Distribute the minus sign
(2 + 7i) - 6 - 8i + (10 - 10i)
Combine like terms
2-6 +10 +7i-8i-10i
6 -11i
multiply 15 by 0.75 and you get $11.25
38.30
because 230 -6x=0
