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

If angle X is an acute angle with tan X = 8/7, what is the value of sec X?

iren [92.7K]

Answer: $\frac{\sqrt{113}}{7}$

Step-by-step explanation:

As X is an acute angle, all 6 trigonometric functions with an argument of X are positive.

Using the identity $1+\tan^{2} X=\sec^{2} X$ ,

$1+\left(\frac{8}{7} \right)^{2}=\sec^{2} X\\\\\sec^{2} X=\frac{113}{49}\\\\\therefore \sec X=\boxed{\frac{\sqrt{113}}{7}}$
