16 it is as easy as multiplying
A or c is the correct answer
Answer:
(11, 13)
Step-by-step explanation:
First Equation: x+y=24
Second Equation: y=x+2
x + (x + 2) = 24
2x + 2 - 2 = 24 - 2
2x/2 = 22/2
x = 11
y = (11) + 2
y = 13
Therefore, the solution to the system is (11, 13)
Answer: C. 
Step-by-step explanation:
1. You have the following division:
(As you can see, to find the conjugate of 4-3i you must change the sign between the terms).
2. To solve this division, you must multiply the numerator and the denominator by the conjugate of the denominator, as following:

3. Keeping on mind that
, you have:

4. Simplifying:

5. The result is:

So if 1in = 15 mi you just multiply each number by 15 to find the number of miles
55) 30 mi
56) 22.5 mi
57) 7.5 mi
58) 48.75 mi
59) 82.5 mi
60) 108.75 mi
