The system of equations that could be used to determine the price of each cookie and brownie:

Given:

To find:

The system of equations that could be used to determine the price of each cookie and brownie.

Solution:

Let the price of a single cookie be x

Let the price of a single brownie be y.

The total price of cookies and brownies paid by Brianna = $9.50

The total price of cookies and brownies paid by Nevaeh = $20.50

it's very simple, use linear question

cookie price =0.25 and brownie price =3

watch solution

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
