Answer:
Infinite solutions
Step-by-step explanation:
<em><u>Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:</u></em>
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n - 2
<em><u>Add like terms (2n and 4n):</u></em>
6n - 2 = 6n - 2
<em><u>Subtract 6n from both sides:</u></em>
-2 = -2
Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.
Answer:
$ 59.5
Step-by-step explanation:
Calculation for how much is the store's profit
First step is to calculate the store's cost
Store's cost= 170/100 * $85
Store's cost =$144.5
Now let calculate the store's profit
Store'sProfit=$144.5-$85
Store's Profit=$ 59.5
Therefore the store's profit will be $59.5
Answer:
If it is that simple then do it yourself LOL
Step-by-step explanation:
Think of it backwards. To get the total measure of the interior angles of a polygon, you divide the polygon into triangles, where a base of each triangle makes up a side of the polygon, and every triangle shares a vertex towards the center of the polygon. We know that the sum of the interior angles in triangles is 180 degrees. Two of the 3 interior angles of each triangle make up the interior angles of the entire polygon. If you add up the third angle of each triangle, you will get 360 degrees. So, the sum of the interior angles of a polygon is equal to the number of sides the polygon has times 180 degrees minus 360 degrees. Written as an expression, you get:
180n-360, where n is the number of sides a polygon has.
Set this equal to 5400 to get the answer:
5400=180n-360
180n=5760
n=32
So the polygon has 32 sides.
It’s -3 mate good luck on your test :)
