Answer:
1225.56 kg
Step-by-step explanation:
1 stone = 14 slugs
1 slug = 14.59 kg
numerator 6 * 14 * 14.59 = 1225.56 kg
denominator = 1
Answer 1225.56 kg in 6 stones
Let j = cost of one jumbo popcorn, and c = cost of one chocolate chip cookie.
Then, based upon the given info, 1j + 2c = $5.
Also, 3j + 5c = $14.50
Let's solve this system of equations using addition/subtraction:
Mult. the first equation by -3, to obtain -3j - 6c = -$15
Now add this result to the 2nd equation:
-3j - 6c = -$15
3j + 5c = $14.50
----------------------
-c = -$0.50, or c = $0.50. Since 3j + 5c = $14.50, subst. $0.50 for c
lets us find j:
3j + 5($0.50) = $14.50, so 3j = $12.00. Thus, j = $4.00.
Jumbo popcorn is $4/bag, and choc. chip cookies $0.50 each.
Part a, and c are OK, point of intersection is the solution. In part b, you can take any point that belongs to f(x), for example: (-3;-2) and (-7,3).
