D = 5x + 10xf solve literal equation for x

Answer:

Yes, the cost in dollars and the quantity of yogurt are indeed proportional.

The relationship can be expressed as:

Step-by-step explanation:

1. If varies directly with , it can be represented as:

Here, represents the constant of proportionality.

2. We'll calculate the proportionality constant. Given that and , we have:

3. Thus, the equation becomes:

4. Now, we need to verify proportionality. Substituting , which is the quantity of yogurt purchased by Jonah, we should arrive at $0.48:

5. They are indeed directly proportional.

To determine the unit rate, divide 1.19 by 12, which gives the cost per ounce. 1.19/12 =.099 per ounce. Since this involves currency, round your answer to two decimal places unless stated otherwise. Rounding.099 results in $0.10 per ounce.

Answer:

Comprehensive explanation:

Let's denote

x -----> the number of days

and

y ----> the remaining minutes for Yuson

We know that

The linear equation in slope-intercept form can be represented as

here

m indicates the slope

b represents the y-coordinate of the y-intercept (starting value)

In this scenario, we have

The slope is defined as

----> negative, as it indicates a decreasing function

----> initial value

substituting the values

Jane must lower the price by 20%

Response:

a)12 b)12 c)36

Detailed steps:

a) Identify the least common multiple. The quantity of marbles corresponds to that value multiplied by n (with n representing an integer)

b) The least common multiple is calculated as 4*3=...

c)12*3 =?

Afterward, simply divide by 2, 3, and 4 to find the solution
