Answer:
$45.50
Step-by-step explanation:
1. $65.00 ÷ 100 = 0.65
2. 0.65 x 30 = $19.50
3. $65.00 - $19.50 = $45.50
3/(3 - 12i)
To simplify this, multiply both sides by (3 + 12i)
(3 - 12i)(3 + 12i)
<em><u>Distributive property.</u></em>
3(3 + 12i) - 12i(3 + 12i)
9 + 36i - 36i - 144i^2
<em><u>Simplify.</u></em>
9 - 144i^2
i^2 can be interpreted as -1.
9 + 144
<em><u>Combine like terms.</u></em>
153 is the simplified version of the bottom half of the expression.
Now for the top half.
3(3 + 12i)
<em><u>Distributive property.</u></em>
9 + 36i
We can simplify this further by factoring.
3(3 + 12i)/153
1 + 4i/17
1/17 + 4i/17 is the simplified version of the expression. (This is your answer.)
Let me know if you have any other questions.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 5
