The point where they intersect
Answer:
Step-by-step explanation:
3c + 5w = 16
6c + 2w = 22
-6c - 10w = -32
6c + 2w = 22
-8w = -10
w = 10/8 = 5/4 = $1.25 per lb
3c + 5(1.25) = 16
3c + 6.25 = 16
3c = 9.75
c = $3.25 per lb
30/54 =x/1,140
30*1140= 34200
34200/54 = 633.33
ANSWER:
Estimated- 633
(a/b) x (c/d) = (a*c)/(b*d)
Therefore:
(9/4) x (1/3) = (9*1)/(4*3) = 9/12 = 3/4
Answer:
3/4
