Select all the situations that can be modeled with an equation. the sale price of a television is $125 off of the original price. anna gave away 5 hats. marco spent twice as much as owen. susan earns $25 per day for d days. ben paid a total of $75 for a shirt and a pair of shoes.

The situations that can be modeled with an equation are:

1. The sale price of a television is $125 off of the original price.

Let the original price of TV be=x

Sale price =

Let sale price be S so equation is : S=

3. Marco spent twice as much as Owen.

Let Owen spent = x

Then Macro spent = 2x

Let Macro spends $y , So, equation becomes

y = 2x

5. Ben paid a total of $75 for a shirt and a pair of shoes.

Let 'x' represent the cost of a shirt and 'y' represents the cost of a pair of shoes then equation becomes:

step-by-step :

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
