Answer:
-33
Step-by-step explanation:
White as system of equations:
a=(3,-2) b=(1-1)
{a=1-1
{(3-2)b=1-1
Solve the equation for a:
{a=0
{(3-2)b=1-1
Solve for B :
a=0
b=0
The possible solution to the system is the ordered pair ( a , b )
Solution:
( a , b )= ( 0 , 0 )
There you have your answer :)
The length is 36 and the width is 15.
Answer: a) 
b) Cost of a macadamia nut chip cookie is $33.93 and the cost of triple chocolate cookie. is $3.77
c) Elimination method because it enables us to eliminate one of the variables.
Step-by-step explanation:
Let x be the cost of macadamia nut chip cookie and y be the cost of triple chocolate cookie.
Then according to the question we have the following equations:-

Multiplying 5 on both sides of the equation (2), we get
...............(3)
By using elimination method, subtract equation (1) from (3) we get

Substitute the value of y in (2), we get
