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
Answer: b
Step-by-step explanation: cut 27 into fourths lol
Answer:
7 is the unit rate.
Step-by-step explanation:
7 because 7x4 is the 28.
12 is the answer.
The sequence is 12, 6, 3, 3/2
1. (3,2)....because when finding the slope, we find the the slope of mn and the slope of op are negative reciprocals.
2. y = 5x - 7.....slope here is 5....perpendicular line has a negative reciprocal slope...so the slope has to be -1/5
y= mx + b
slope(m) = -1/5
(-10,3)...x = -10 and y = 3
now we sub and find b, the y int
3 = -1/5(-10) + b
3 = 2 + b
3 - 2= b
1 = b
so ur perpendicular equation is : y = -1/5x + 1
