You have a gift card for your favorite clothing store for the amount of $60. You have found a shirt you want for $15. You don't

Zolol [24]

Let

x--------> the amount you have left to spend

y--------> the cost of a shirt you want

z------> the amount of the gift card

we know that

$x+y \leq z$ --------> equation $1$

$y=\$ 15$ --------> equation $2$

$z=\$ 60$ --------> equation $3$

Substitute the equation $2$ and equation $3 in the equation [tex] 1$ [/tex]

$x+y \leq z$

$x+15 \leq 60$

therefore

<u>the answer is the option</u>

x+15 is less than or equal to 60

Johanna, Elizabeth, and Dan are preparing a chemical solution for a research project. When

Bond [772]

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.

<h3>What is the together rate?</h3>

It is the sum of each separate rate.

In this problem, the rates are given by:

Johanna's: 1/6.

Elizabeth's: 1/6.

Dan's: 1/4.

Hence the together rate is given by:

$\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}$

$\frac{1}{x} = \frac{1}{3} + \frac{1}{4}$

$\frac{1}{x} = \frac{4 + 3}{12}$

7x = 12

x = 12/7

x = 1.71.

They would prepare the solution in 1.71 minutes working together.
