Let the number be Y .
Y is seven
less than 5 times another (let that other be X)
Y=7-5X
sum of both Y and X minus 4 gives one
Y+X-4=1
now solve both equations .
In 1414 hours it covered 700 miles
In 1 hour it would have covered (700/1414) mile
In 33 hours it will then cover : 700/1414 * 33 = 16.34
So in 33 hours it will cover ≈ 16.34 miles.

Answer:
solve for x
x=2
Step-by-step explanation:
x2-20x-17=-53
reorder like terms x2= 2x 2x=20x-17=-53
collect like terms 2x-20x=-18x -18x-17=-53
move constant to the right hand side and change its sign -18x=-53+17
calculate the sum -53+17= -36 -18x=-36
divide both sides by -18 -18x÷-18= x -36÷-18=2
x=2
I Believe it would remain the same unless there is a fee for converting the dollar to yen in the first place.
