Answer:
One pound costs 1.26, two costs 1.47, three costs 1.68, and four costs 1.89. So we calculate how much it increases in each pound.
1.26 + 21 = 1.47
1.47 + 21 = 1.68
1.68 + 21 = 1.89
1.89 + 21 = 2.10
2.10 + 21 = 2.31
2.31 + 21 = 2.52
2.52 + 21 = 2.73
8 pounds cost: 2.73
So I pay $ 2.73 for 8 pounds.
Answer:
(x, y) = (2, 2)
Step-by-step explanation:
The problem statement tells us ...
GK : GJ = 3/5 . . . . the given ratio
5(GK) = 3(GJ) . . . . multiply by 5(GJ)
5(K-G) = 3(J-G) . . . replace segment lengths with endpoint differences
5K -5G = 3J -3G . . . eliminate parentheses
5K = 3J +2G . . . . . add 5G
K = (3J +2G)/5 . . . . divide by 5
K = (3(6, 0) +2(-4, 5))/5 = (18 -8, 0+10)/5 . . . . substitute point coordinates
K = (2, 2)
The values of x and y are both 2.
