Answer:
B) 6(x+2y) + 4 = 6x + 12 y + 4
t = time to hike up the hill
3-t is the time to hike down the hill
so 4t = 6(3-t)
4t = 18-6t
10t = 18
t = 18/10 = 1.8 hours to hike up the hill
1.8 hours = 1 hour 48 minutes
Answer:

Step-by-step explanation:
240-35= 205

170-35=135 (Or just use a calculator)
Answer:
y = 6
Step-by-step explanation:
We need to interpret the question
y varies directly as x
y varies x
To equate it, we need to add a constant K
y = K/x
Using the information we are provided with
y = 9
x = 3/2
insert into
y = Kx
9 = K * 3/2
9 = 3K/ 2
3K = 9 *2
3k = 18
To get K, divide through by 3
3K/3 = 18/3
K = 6
Since we've gotten our K = 6
y = Kx
Using the new information
y = ?
x = 1
K = 6
y = 6* 1
y = 6
The new y = 6 , x =1
