Arnie is an American teaching English in Japan, and he currently has 55,000
yen in his bank account. If the exchange rate changes from 1 U.S. dollar=
90.77 Japanese yen to 1 U.S. dollar = 91.24 Japanese yen, what happens to
the value in U.S. dollars of the money in Arnie's bank account?
Answer:
The worth of his bank account in USD would go from $605.93 to $602.81 cents. This is because it due to the change in exchange rates it requires more yen to make up a dollar which would cause it to take more yen to make a dollar. I hope this helps :D
Solve: 2 x + 5y + 5 = 0
2y=3x+17.
Find x and y
Answer:
x = -5 and y = 1
Step-by-step explanation:
a) 2x + 5y +5 = 0
a) 2x + 5y = -5
b) 2y = 3x + 17
b) y = 3/2x + 17/2
a) 2x + 5(3/2x + 17/2) = -5
a) 2x + 15/2x + 85/2) = -5
a) 19/2x = -5 - 85/2
a) 19/2x = -95/2
a) x = (-95/2) / (19/2)
x = -5
b) 2y = 3(-5) + 17
b) y = 2/2
y = 1

Scott walks to and from school each day. Each round trip is 3 kilometers long.
Write an equation that shows the relationship between the number of round trips, x, and the
number of kilometers Scott has walked in all, y.
The equation that shows the relationship between the number of round trips, x and the number of kilometers, y Scott walked is y = 3x
Each round trip = 3 km
x = number of rounds
y = number of km he has walked in all.
1 rounds = 3 km
Therefore,
x rounds = 3x km
Each round of trip covers 3km. This means for each round of trip a distance of 3km is covered. The total distance or number of kilometers is represented with y.
The equation to show the relationship between x(number of rounds) and y (number of km) can be represented below
