-BARSIC- [3]

Answer:

B. 225 - 45 = 10d

Step-by-step explanation:

The remainder Ezra needs to save can be earned by walking ten dogs.

Let remainder = r

Let dogs = d

This means:

r = 10d

Make 'r' numerical values.

r = Total cost of snowboard - Current savings

r = $225 - $45

Therefore:

225 - 45 = 10d

soldier1979 [14.2K]

Option B

48 = 2s - 3 shows an equality between number of political articles that Reggie wrote this year

<h3>Solution:</h3>

Given that, Reggie wrote a total of 48 political articles for the town newspaper this year

Number of political articles = 48

Let s represent the number of sports articles he wrote

The number of political articles he wrote is 3 less than twice the number of sports articles he wrote

Number of political articles = twice the number of sports articles - 3

Number of political articles = (2 x number of sports articles) - 3

Number of political articles = 2s - 3

We know that, number of political articles = 48

48 = 2s - 3

Thus above equation shows an equality between number of political articles that Reggie wrote this year

For the equation ae^ct=d, solve for the variable t in terms of a,c, and d. Express your answer in terms of the natural logarithm

saveliy_v [14]

We have been given an equation $ae^{ct}=d$ . We are asked to solve the equation for t.

First of all, we will divide both sides of equation by a.

$\frac{ae^{ct}}{a}=\frac{d}{a}$

$e^{ct}=\frac{d}{a}$

Now we will take natural log on both sides.

$\text{ln}(e^{ct})=\text{ln}(\frac{d}{a})$

Using natural log property $\text{ln}(a^b)=b\cdot \text{ln}(a)$ , we will get:

$ct\cdot \text{ln}(e)=\text{ln}(\frac{d}{a})$

We know that $\text{ln}(e)=1$ , so we will get:

$ct\cdot 1=\text{ln}(\frac{d}{a})$

$ct=\text{ln}(\frac{d}{a})$

Now we will divide both sides by c as:

$\frac{ct}{c}=\frac{\text{ln}(\frac{d}{a})}{c}$

$t=\frac{\text{ln}(\frac{d}{a})}{c}$

Therefore, our solution would be $t=\frac{\text{ln}(\frac{d}{a})}{c}$ .
