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
Step-by-step explanation:
a,b) you can place all 17 in the middle and both circle will have 17 each. then remove 2 and place one each on separate sides. you can do this 8 times so that at the you'll end up with 1 in the middle and 8 each on separate sides.
the ways to do is then 9.
Answer:
Increase:
It will have increase when y>x
so, percentage of increase is
Decrease:
It will have decrease when x>y
so, percentage of decrease is
Step-by-step explanation:
Let's assume initial value as x
assume final value as y
Increase:
It will have increase when y>x
so, percentage of increase is
For example:
Initial value is 40
So, x=40
Final value is 50
so, y=50
now, we can find percentage in increase
Decrease:
It will have decrease when x>y
so, percentage of decrease is
For example:
Initial value is 50
So, x=50
Final value is 40
so, y=40
now, we can find percentage in decrease
