Answer:
Step-by-step explanation:
You can solve this by representing these two statements into equations and solving for one of the variables. Here, I will use x and y, where x > y.
Now, we can choose which variable to solve for. I'm going to isolate one of the variables in the first equation by subtracting y from both sides.
Using this equation, we can substitute it for the x variable in the second equation like this:
Simplifying this, we get
Solving this, we find that y = 15. We can plug this into one of the equations to find x:
Solving for this equation, we find that x = 28.

Step-by-step explanation:
Distance from,
There = 50
and Back = 50
speed is...
There = 25+5
Back = 25-5
50/25+5 = 50/30 = 5/3
50/25-5 = 50/20 = 5/2
5/3+5/2 = Total Time spent to go from pier a to pier b and back
Total Time = 25/6 Hours
Answer: 7 years
Step-by-step explanation:
let x be the age of Mary
so John's age will be 2x
the equation becomes
2x+x=21
3x=21
x=21/3
x=7
