The answer is 56 cookies because i did math in my head
Answer:
the GCF is 3 so 2b - 3k
Step-by-step explanation:
To answer this question you should begin with the coin that has a higher value. If you start with the dime and then just add the correct number of pennies to total $0.40, you will see that you will need 3 dimes ($0.30) and 10 pennies ($0.10).
I used a guess and check strategy starting with 2 dimes.
- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1
at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c
c = -1 -1
c = - 2
equation:
y = -x -2
y + x = -2 or - x - y = 2
2/3 of the journey = 6 miles
1 (whole journey ) = 6 / 2/3 = 6 * 3/2 = 9 miles answer
