M = Tim's dollar amount
R = Rebecca's dollar amount
MR = Tim and Rebecca's dollars together
R = (M x 1/10) - 6
MR = M + ((M x 1/10) - 6)
MR = 70 + ((70 x 1/10) - 6)
MR = 70 + (7 - 6)
MR = 70 + 1
MR = 71
Answer: B) 0
Step-by-step explanation:
1. When you add complex numbers you must add the whole parts and then the imaginary parts.
2. One of the properties of complex numbers is called "Additive identity" which is represented by:
3. Then, for the complex number 
, you have:
4. Therefore, the answer is the option B.
Ur answer is (0,-3)
because ur line is a solid line, this means any number on that line is a solution....along with any points that are in the blue area. when u plot ur answer choices, if it falls in the white area, it is not a solution
6(15) + 10b > = 200
90 + 10b > = 200
10b > = 200 - 90
10b > = 110
b > = 110/10
b > = 11
so she can do 15 days of running plus 11 days of biking....which totals 26 days
Gordon gets £72
Explanation:
Sarah gets twice as much as Gordon and Gordon gets three times as much as Malachy, which means that Malachy gets 1 part of the money, Gordon gets 3 parts because he has three times as much as Malachy, and Sarah gets 6 because she gets twice as much as Gordon. As a ratio from Sarah to Gordon to Malachy its 6:3:1. All of that adds up to £240. If u add 6+3+1 it gives you 10. 240/10 is £24. And Gordon has 3 parts so you do 3x24 which gives you £72
