Answer:
n = -13
Step-by-step explanation:
√10 - 3n = 7 ⇔
⇔ 10 - 3n = 49 ⇔ We need to remove the square root. Ex: √n = 2 ⇔ n = 2²
⇔ -3n = 49 - 10 ⇔
⇔ -3n = 39 ⇔
⇔ n =
= -13 (as -3 changes members, as it was multiplying, it now divides, conversion).

Answer:
x = 7
y = -7/2
Step-by-step explanation:
(x+6i)=(3-i)+(4-2yi)
First look at the real parts
x = 3 +4
x = 7
Then look at the imaginary part
6i= -i -2yi
6 = -1-2y
Add 1 to each side
6+1 = -2y
7 = -2y
Divide by -2
7/-2 = y
60*80/100-$10*155/100
48-$10*155/100=$58.90
What you need to do is add the two equations and combine like terms to get h(x). Refer to the photo for a better explanation.
