Ar if you are you streaming service offers unlimited movies for $15 per month or 1.99 per movie if you want to watch a movie's which is the better deal

$1.99 per movie.

Step-by-step explanation:

if you watch 8 movies or more a month, $15 per month is better value. ($1.99 × 8= $15.92)

if you watch 7 movies or less, $1.99 per movie is better value. ($1.99 × 7= $13.93)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
