Answer:
x>1
Step-by-step explanation:
20 < 5x +15
20 - 15 < 5x
5 < 5x
1< x
x>1
Step-by-step explanation:
answer is d and b.
they both lie in same line
The answer is A. c and d don't have the numbers and B has them backwards.
Answer:
2) 8/18 = 0.444444
9) -0.9 = -9/10
Step-by-step explanation:
Distance traveled is directly proportional to time traveled.
d α t
d = kt, where k is constant of proportionality.
Using d = 93 miles and t = 15 hours
93 = k(15)
15k = 93
k = 93/15 = 6.2
Hence variation equation is: d = kt, since k = 6.2.
d = 6.2t
Distance traveled in 24 hours:
d = 6.2t
d = 6.2*24
d = 148.8
Distance traveled is 148.8 miles.
