Hello,

There are 24 hours in a day. If 25% of your day is spent at school, then you spent (24)(0.25) = 6 hours at school.

If 8% of your day is spent eating, then you spent (24)(0.08) = 1.92 hours eating.

Together, this is 6 + 1.92 = 7.92 hours ≈ 7.9 hours spent at school and eating in one day.

Hope this helps!

Answer:

Solutions: b, c, d, e

Not Solutions: a

Step-by-step explanation:

There are two ways to solve this problem: you could graph the system and check which points fall in the solution set or you could substitute the $x$ and $y$ values of each point into the inequalities that make up the system. I'm going to use the former because it's quicker, in my opinion.

Step 1: Graph

Rewriting the first inequality gives us:

$2x+5y$

$5y$

$y$

To graph this, draw the line $y=-\frac{2}{5}x +2$ and then, because the sign is " ", shade below the line and make it a dashed line. This is the red inequality on the graph.

Rewriting the second inequality gives us:

$3x-4y\geq -8$

$-4y\geq -3x-8$

$y\leq \frac{3}{4}x+2$

To graph this, draw the line $y\leq \frac{3}{4}x+2$ and then, because the sign is " $\leq$ ", shade below the line and keep it a solid line. This is the blue inequality on the graph.

The solution set of the system will be the region where the two shaded areas overlap, which is the purple area.

Step 2: Check Points

Now, all we need to do is check whether each point lies in the purple region on the graph.

$(3,5)$ lies above the purple region, but it isn't in the region, so it is not a solution to the system.

$(-2,10)$ does lie in the purple region, so it is a solution to the system.

$(5,-12)$ does lie in the purple region, so it is a solution to the system.

$(-6,-8)$ does lie in the purple region, so it is a solution to the system.

Finally, $(0,0)$ lies in the purple region, so it is a solution to the system.

Hope this helps!

You are buying an area rug for your bedroom. The area of your room you want to cover is 40 feet squared. You find that the lengt

Kamila [148]

The length and the width of the rug having an area of 40 square feet will be 5 feet and 8 feet respectively.

Area is defined as the space covered by any object in the two dimensional plane. Here it is given that the area of the rug should be 40 square feet and the length of the rug is 3 less then its width.

So to find out the length and the width we will form an equation.

Let the width is = x feet

So the length will be = x-3 feet

Now the area will be

$x(x-3)=40$
