(x+y)+(x-y)i=7+3i
x+y =7
x-y =3
add these two equations together
x+y =7
x-y =3
------------------
2x = 10
divide by 2
x=5
x+y = 7
5+y =7
subtract 5 from each side
y =2
Answer: x=5
y=2
Answer:
68
Step-by-step explanation:
(n+2)/5=14
n+2=14*5
n+2=70
n=70-2
n=68

Step-by-step explanation:
$332.64
20% of 415.80 is 83.16
415.8-83.16=$332.64
Answer:
see explanation
Step-by-step explanation:
The measure of arc MP = 360° - measure of arc PM, that is
arc MP = 360° - 210° = 150°
x is half the measure of the intercepted arc MP, thus
x = 0.5 × 150 = 75
