Mrs. Ellington has a $50 gift card to Best Buy. She purchased a DVD for $28. Which inequality shows all possible values for x, t

Effectus [21]

Answer:

4th option

Step-by-step explanation:

She purchased a DVD for $28.

$50 - $28 = $22

1. 22 < 22

2. 22 > 22

3. 22 < 78

4. 22 > 78

I would say it would be the 4th option because she can only spend less than 78.

I can be very incorrect though, don't depend on me that much. Just make sure to think about my answer and what you would answer.

Evaluate x/y when x=9/4 and y=3/5

lana66690 [7]

Answer:

$\displaystyle x/y=\frac{15}{4}$

Step-by-step explanation:

<u>Division of fractions</u>

To calculate the division of fractions a/b and c/d, it's usually easier to multiply a/b by the reciprocal of the denominator, that is:

$\displaystyle \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}\cdot \frac{d}{c}$

We will evaluate x/y when x=9/4 and y=3/5:

$\displaystyle \frac{\frac{9}{4}}{\frac{3}{5}}=\frac{9}{4}\cdot \frac{5}{3}$

$\displaystyle=\frac{45}{12}$

Simplifying:

$\displaystyle \boxed{x/y=\frac{15}{4}}$
