Let's solve number 7 step-by-step.
y/23=7
Step 1: Multiply both sides by 23.
y/23=7
(y23)*(23)=(7)*(23)
y=161 is our answer.

Let's solve number 8 step-by-step.
n−4.85=12.6
Step 1: Add 4.85 to both sides.
n−4.85+4.85=12.6+4.85
n=17.45 is our answer.


Let's solve number 12 step-by-step.
m/5=8
Step 1: Multiply both sides by 5.
m/5=8
(m/5)*(5)=(8)*(5)
m=40 is our answer.


Let's solve number 16 step-by-step.
a/12=8
Step 1: Multiply both sides by 12.
a/12=8
(a/12)*(12)=(8)*(12)
a=96 is or answer.

Calculate 6+9i/-1+4i

lisabon 2012 [21]

Multiply the numerator and denominator by the conjugate of the denominator:

$\dfrac{6+9i}{-1+4i} \times \dfrac{-1-4i}{-1-4i} = \dfrac{(6+9i)(-1-4i)}{(-1)^2-(4i)^2}$

Simplify:

$\dfrac{(6+9i)(-1-4i)}{(-1)^2-(4i)^2} = \dfrac{-6-9i-24i-36i^2}{1-16i^2} = \dfrac{-6-33i-36i^2}{1-16i^2} = \dfrac{-6-33i+36}{1+16} = \boxed{\dfrac{30-33i}{17}}$
