The first option is the right answer
E = 352.50 euro × 1 pound / 1.41 euro = 250.00 pounds
J = 39856 yen × 1 pound / 188 yen = 212.00 pounds
a) Japan is cheaper
b) 250 - 212 = 38 pounds cheaper
30 of them 30 +30+30+30=120 each of the 30 represents 25%
Answer:
x = 11.2
Step-by-step explanation:
-5x - 12y = -8
5x + 2y = 48
you can combine all like terms from both equations together:
0x-10y=40
simplified:
-10y=40
y=-4
now you plug in the value of y into either equation:
5x+2(-4)=48
simplify
5x-8=48
add 8
5x=56
divide by 5
x=56/5=11.2
Answer:
Irrational number
Step-by-step explanation:
It's given,
y = (By simplifying the product of rational number 'x' and an irrational number 'y')
Where m and n are the integers and is a rational number.
(Since x = is a rational number)
Therefore, will be a rational number.
y = ⇒ Irrational number = Rational number
which is a contradictory statement.
Therefore, multiplication of rational and irrational number will be irrational.
