Anthony purchased 6 fruit bars and 3 chocolate-nut bars for a camping trip. he spent $4.12 on the bars. anthony wrote the following equation: 6x+3y=4.12 . what did he define as the variable x?

He defined variable x as the cost of each fruit bar.

Step-by-step explanation:

6 is the amount of fruit bars Anthony has, so 3y must be for the chocolate-nut bars. So the only thing that makes sense is if variable x is the cost of each fruit bar.

A cost a friut bar

Step-by-step explanation:

just finished the test and that was correct have a great day or night!

Add 10 both sides
(x-4)^2=25
sqrt both sides
remember to take positive and negative roots
x-4=+/-5
add 4
x=4+/-5

it is because the square  of z is the same as the square of -z for example

it is becasue of of the property of squareing numbers
