Four times a number is equal to the number increased by 15. Enter the equation that represents Karla's sentence into the box. Us
Montano1993 [528]

Answer:

The equation that represents Karla's sentence is 4y = y + 15

Step-by-step explanation:

From the question,

Four times a number is equal to the number increased by 15. To write the equation that represents the sentence, we will have to use a variable to represent the unknown number.

Since we are asked to use y for the variable, that is, let the number be y

Then

The statement, "four times a number" will be

4×y = 4y

and this is equal to the number increased by 15,

The number increased by 15 means y + 15.

Hence, the equation becomes

4y = y + 15

This is the equation that represent Karla's sentence.

If desired,

The unknown number can be determined by solving for y in the equation

4y = y + 15

First, Collect like terms

4y - y = 15

3y = 15

Then, Divide both sides by 3

3y/3 = 15/3

y = 5

Hence, the variable (unknown number) is 5.

Plz help!!
AlexFokin [52]

Answer: 50 Books

Step-by-step explanation:

B = number of books in Ruben's collection BEFORE he bought new ones.

So  6 books were bought which increased his collection by 12%.

12% as a decimal would be 0.12..then we add the variable which represents the number of books, 0.12B.

So then we know 0.12=6

*We need to isolate the variable* So we would divide 0.12 on both sides. 0.12/0.12 and 0.12/6 which is 50.

Hope this helps! :)
