Answer:
B. 3 / (x+6)
Step-by-step explanation:
3(x+2)/(x+6)(x+2) = 3 / (x+6)
Number 1: (-1+2i)+(6-9i)
Number 2: (3-3i)-(4+7i)
Number 3: (-5+2i)+(-2+8i)
Answer:
T = 7.5
Step-by-step explanation:
One table = 4 students
? table = 30 students
To get the answer we criss-cross
30 * 1 = 4T(amount of table)
4T = 30
T = 30/4
T = 7.5
There should be 8 tables but the last table has 2 people sitting on it rather than 4.

Answer:
The cost of the dinner before other costs is $14.20
Step-by-step explanation:
To solve this, we write the following equation:
x + .11x + .20x = 18.60
This is because in addition to paying for the dinner (x), she also has to pay 11% of it and another 20% of it. Now we can combine like terms and solve.
1.31x = 18.60
x = 14.20
