Answer: y = 6

Step-by-step explanation:

A square's area can be done by using s^2, where s is y in this case.  Because there are 5 squares, the area of the figure is 5y^2.  Because the area is also 180cm, 5y^2=180.

Then divide both sides of the equation by 5 to get y^2 = 36.  Then square root both sides of the equation to get y = 6.

Hope it helps <3

You are planning your week-end schedule. You can spend at most 8 hours playing video games and doing homework. You want to spend
MatroZZZ [7]

The system of inequalities is:

v + h ≤ 8

v < 2

h ≥ 1.5

<h3>Which system of equations represents this situation?</h3>

Let's define the variables:

  • v = number of hours playing video games.
  • h = number of hours spent on homework.

The maximum time that you can spend on both activities is 8 hours, then:

v + h ≤ 8

You want to spend less than 2 hours on video games, so:

v < 2

You want to spend at least, 1.5 hours on homework, so:

h ≥ 1.5

Then the system of inequalities is:

v + h ≤ 8

v < 2

h ≥ 1.5
