To determine a monthly budget for gasoline, Rachael determines that she can not spend more
IrinaK [193]

The solution of the given inequality is:

x ≤ 15.24

<h3>How to solve the inequality?</h3>

We know that the maximum that she can spend on gasoline is the 12% of $400.

That is:

(12%/100%)*$400 = 0.12*$400 = $48

Now, we know that each gallon of gas costs $3.15, then if x is the number of gallons of gas that she buys, we have the inequality:

x*$3.15 ≤ $48

To solve the inequality, we need to divide both sides by $3.15

x ≤ $48/$3.15

x ≤ 15.24

So the maximum number of gallons of gasoline that she can buy is 15 gallons (actually a little more).

How do you do inverse operation on a fraction ( y/3 ) = -6
NemiM [27]

\frac{-1}{18}

Solution:

Given expression is \frac{y}{3}=-6

To find the inverse of y.

⇒ \frac{y}{3}=-6

Do cross multiplication.

⇒ y = –6 × 3

⇒ y = –18

Inverse of y means reverse the function.

We know that inverse of y is \frac{1}{y}.

⇒ \frac{1}{y}= \frac{-1}{18}

Hence, inverse of y is \frac{-1}{18}.
