Answer:
The slope is 2/3x and the y-intercept is 5.
Answer:Let t = cost per pound of turkey
Let h = cost per pound of ham
4t + 2h = 30
t = h - 1.5
substitute h-1.5 in place of t in 1st equation
4(h-1.5) + 2h = 30
4h - 6 + 2h = 30
6h - 6 = 30
6h = 36
h = 6
t = h-1.5 = 4.5
1 pound of turkey costs $4.50
1 pound of ham costs $6.00
----------
cost of 1 pound each $10.50

Answer: C
Step-by-step explanation:I did the test.
The length of the other train is 220m.
Length of the train= 270m
Speed of the train = 120kmph
Speed of the other train = 80kmph
Time required to cross the trains = 9 seconds
Let the length of the other train be x m
We know that,
Speed*time = distance
We know that,
Relative speed of train w.r.t to the other train = 120 +80 = 200kmph = 200*5/18 = 500/9 m/s
Distance = (270 + x) m
Time = 9 seconds
Hence,
(270 + x) = 500/9*9
270 + x = 500
x = 500 - 270
x = 220m
