To find the constant variation, solve for only one hour (in this case).
Divide 100 with 2
100/2 = 50/1
Each hour is 50 miles driven, so your constant variation is 50 mph
6-6x= -24
Subtract 6 from -24 = -30
divide -30 by -6= 5
x=5
Answer:
1. 23/20 miles, 2. 7/20 miles
Step-by-step explanation:
1. Total distance = 3/4 + 2/5
= (3*5)/(4*5) + (2*4)/(5*4)
= 15/20 + 8/20
= 23/20
= 1 3/20 miles
2. Difference between walked miles and jogged miles = 3/4 - 2/5
= 15/20 - 8/20
= 7/20 miles
Answer:
46.5
explanation
6.022*10^23 molecules=40g.
7.00*10^23=40*7.00*10^23/6.022*10^23 g =46.5 g
The correct answer is y=2/3x+4 which is the last option :)
