Answer:
16y+2
Step-by-step explanation:
8x2y=16y
8x1/4=2
V=s/t
s=300 km = 300000 m
t=1 h and 30 min = 5400 sec
v=300/1,5= 200 km/h
or
v=300000/5400=55,5 m/s
Answer:
No solution
Option 4 is correct
Step-by-step explanation:
Given: The system of inequality


We need to choose correct option.
Option 1: (-5,2)
Put x=-5 and y=2
Equation 1 Equation 2


TRUE FALSE
Option 2: (2,2)
Put x=2 and y=2
Equation 1 Equation 2


FALSE FALSE
Option 3: (5,2)
Put x=-5 and y=2
Equation 1 Equation 2


FALSE TRUE
Option 1, 2 and 3 are incorrect because both equation must be true for solution.
Hence, Option 4 is correct no solution.

Answer:
The fourth choice.
Step-by-step explanation:
Because since 90 miles is basically counted as your first day, you do the number of days, n, minus 1 and then multiply it by 5 to find the number of miles walked after the first day. Then you add it to 90.
