andrey2020 [161]

Answer:The cost of one month of game-play =$20


Step-by-step explanation:

and Then cost of game-play bought by Kenny=4x......(2)

Cost of each software package =$50......(3)

⇒140=7x⇒x=20.....→( dividing both sides by 7 )

Find the measure of each interior angle of the regular polygon (The polygon has 12 sides)​
Nostrana [21]

Answer:

150°

Step-by-step explanation:

To find the sum of all the interior angles in a regular polygon, us this formula, where n is the number of sides: (n-2)*180

(12-2)=10

10*180=1800

Now we have the sum of all the angles. But we aren't done yet! We have to divide this value by the number of sides to find the measure of one angle.

So,

1800/12=

150

Hope this helps!

Determine whether the system of equations has no solution, one solution, or infinitely many solutions
Vinil7 [7]

Answer:

one solution

Step-by-step explanation:

y=-3x+5

y=1/2x-2

You can tell straight off the bat, it does have a solution, and it isn't infinite solutions. If it had no solution, it would have the same slope but different y-intercepts. If it had infinite solutions, the 2 equations would have to be the exact same. So there is only one solution.

hope it helps
