Sam Ordered Some Books Online For $5 Each. He Paid A Total Of $4 For Shipping. The Total Cost Of The

Answers

Answer 1

Answer:

17

Step-by-step explanation:

if you subtract 4 from 89, which is the shipping cost. 89 - 4 = 85. Then divided 85 by 5 because that will show how much he paid for them in total, by how much a singular book is. Telling you how many books he bought. 85/5 = 17.

Answer 2

Answer:

A.) 5b+4=89

B.) 17 books

Step-by-step explanation:

To find A.), we must create a linear equation. Let b be the number of books Sam ordered. We write 5b because each book is 5 dollars. Then we add 4 dollars to the equation to represent the shipping fee. Then we write "equals to 89",  because it says that is the total cost. So we get the equation 5b+$4=$89

To find B.), we must solve the equation. Isolate the variable, by subtracting 4 from both sides. We then get 5b=$85. Now we divide by 5 to get only the variable and to get rid of the coefficient. We get b=17. So Sam bought 17 books.

Answer:

[tex]\huge\boxed{x=\frac{4d}{ty}}[/tex]

Step-by-step explanation:

If we have an equation ([tex]4d=txy[/tex]) and we want to solve for x, we want to reverse the equation until we have x on one side. Basically - what's stopping x from being alone?

The answer would be the t and the y that are being multiplied by x. So we can divide both sides by t and y to get our answer.

This is the same as dividing both sides by [tex]ty[/tex].

[tex]4d \div ty = txy \div ty[/tex]

[tex]\frac{4d}{ty}=x[/tex]
