The initial payment per month being 30 and each movie being 2.50 means that if the total payment is 45 then you pay for 6 movies per month, 30x+6(2.5x)
Complementary angles add up to 90 degrees.
So we can write:
42 + x = 90
To solve, subtract 42 to both sides:
x = 48
So the complement of a 42 degree angle is a 48 degree angle.
(x+12)^2 = 0
x + 12 = 0
x = - 12

-2p <20-4
-2p <16
-2p/-2 <16/-2
p> -8
Add 5 on both sides and it will give you ×=-10
