Fisrt is solve the distance of the segments using distance formula

Distance =sqroot[(x2−x1)^2+(y2−y1)^2]

So ditance of RS = 5

ST = 8.49

TR =6.08

The using herons formula

Area = sqrt ( s ( s-a) ( s-b) ( s-c) )

Where s s = 1/2 ( a + b + c )

And a, b , c are length of the sides

S = 9.785

Area = 14.99

You have $25 to buy 6 fishing lures. Write and solve an inequality that represents the prices you can pay per fishing lure.
Rus_ich [418]

We are given that we have $25 to pay for 6 fishing lures.

We can make an equality for this as follows:

Suppose price of one fishing lure is x dollars.

So we will use unitary method to find price of 6 fishing lures.

Price of 6 fishing lures = 6 * ( price of one fishing lure) = 6* x = 6x

Now we only have 25 dollars with us, so the price of 6 fishing lures has to be less than or equal to 25 dollars.

So creating an inequality,

6x\leq25

Now in order to find price for one fishing lure, we have to solve this for x.

Dividing both sides by 6 we have,

x\leq\frac{25}{6}

Converting to decimal,

x\leq4.167

Answer : The price of one fishing lure must be less than or equal to $4.167
