Answer:
The total number of CDs sold is 30, and the number of videos is 10.
Step-by-step explanation:
Consider A is the number of Videos sold.
Consider B is the number of CDs sold.
So,
A+ B= 40, B=40 -A
and
$6*A+ $4*B=$180
Replacing, B=40 -A in the second equation
$6*A+ $4*(40 -A)=$180
Distributive property
$6A+ $160 -$4A=$180
$6A -$4A=$180 - $160
$2A=$20
A=$20/$2=10
and B=40 -A, so B=40-10=30
That means, the number of Videos sold is 10
And the number of CDs sold is 30
Answer:
Step-by-step explanation:
(4-5i)(3-6i) = 4*(3-6i) - 5i(3 - 6i)
= 4*3 - 4*6i - 5i*3 + 5i*6i
= 12 - 24i - 15i + 30i²
= 12 - 39i + 30 * (-1) {i² = -1}
= 12 -30 - 39i
= -18 - 39i
