Answer:
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = 
km/min
Time taken up the hill = 
minutes
Speed of Wilmer down the hill = 
km/min
Time taken up the hill = 
minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
Distance up the hill = 
Distance down the hill = 
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
The student weighs 108.8 pounds on saturn. 85x2.34=198.9 -90.1 = 108.8
Hello!
You can make two expressions based on what you know
let x equal the larger number
let y equal the smaller number
x + y = 95
x + 2y = 120
We can use elimination to get rid of x
You can subtract the two equation to get rid of x
-y = -25
Since y is negative we can multiply both sides by -1 to make y positive
y = 25
Now we can put this into one of the other equations to find x
x + 25 = 95
subtract 95 from both sides
x = 70
The answers are 70 and 25
Hope this helps!
Answer:B
