3. shopping at savers mart, lisa buys her children four candy bars and three pops for
$10. she returns the next day and buys three candy bars and five pops for $13. what
is the price of each candy bar and each pop?

Candy bar: $1/each

Pop: $2/each

Step-by-step explanation:

4x+3y=10

3x+5y=13

Where x = number of candy bars and y = number of pops.

Create an augmented matrix like so

Using Gaussian Elimination reduce the matrix to reduced row echelon form.

As you can see x = 1, and y = 2.

Thus each candy bar is $1 and each pop is $2.

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
