Answer: Marcus travels at 5mph and Cody travels at 11mph
Step-by-step explanation:
x = Marcus
x + 6 = Cody
4(x + x + 6) = 64
4x + 4x + 24 = 64
8x + 24 = 64
8x = 40
40/8 = 5
5 + 6 = 11
Marcus = 5 Cody = 11
4*5 + 11*4 = 64
Answer:
median= 6.5
Step-by-step explanation:
6= 2+5+x+1+x+2+7+9/6
summing up the values
26+2x=36
collecting like terms,
2x=10
divide both sides by 2
x= 5
5+1=6
5+2=7
so the numbers are 2 5 6 7 7 and 9
the median = 6+7/2
= 6.5
The answer would be B because the 100 stays in there and you are adding 8% per year. Hope this helps.
