Question

MEDAL AND FAN
Which of the systems below is equivalent to the given system?

0.01 x - 0.05 y = 0.1
0.4 x + 0.3 y = 0.9

10 x - 5 y = 10 and 4 x + 3 y = 9
x - 5 y = 10 and 4 x + 3 y = 9
x - 5 y = 1 and 4 x + 3 y = 9

Answer 1

T.T

Answer 3

Which one looks the slightest bit closest to you?

Answer 4

10 x - 5 y = 10 and 4 x + 3 y = 9

Answer 5

Its trial and error multiply them by either 10,100 or 1000

Answer 6

Since youve chosen the 1st option, my guess is youve multiplied the first equation by 1000 and the second by 10.
So, it should look like
1000(0.01 x - 0.05 y = 0.1) = 10x - 50y=100
10(0.4 x + 0.3 y = 0.9) = 4x + 3y = 90

Answer 7

yes

Answer 8

But the answer doesnt resemble with that of the option given so, if you calculate them properly

Answer 9

ok

Answer 10

x - 5 y = 10 and 4 x + 3 y = 9

Answer 11

10x - 50y=100 is not the same as 10 x - 5 y = 10, so option 1 is incorrect

Answer 12

Can you demonstrate your conclusion?

Answer 13

im guessing because i need to do this rfast

Answer 14

Ok, option 2 is the correct answer because if you were to multiply 100 and 10 to the respective equations;
100(0.01 x - 0.05 y = 0.1)
10 (0.4 x + 0.3 y = 0.9)
you'll get the exact answer as the one you've given above
x - 5 y = 10 and
4 x + 3 y = 9 .
