If Tim rounded his number to 5.46, the smallest number he could've thought of would be 5.455. This is because if the third decimal digit of a number is five or greater, the second can be rounded up.
I believe this is correct.
Substitute into second equation:
x+3=2x-3
put variables on one side:
3x=6
x=2
Substitute to find y:
y=2+3
y=5
So (x, y) = (2, 5)
35*75 is
2625
2625/400 is
6.5625

Answer:
Any from 1:3.5 , 4:14 , 6:21 (etc) would be equal to 2:7
Step-by-step explanation:
2 divided by 2 would be 1, and 7 divided by 2 would be 3.5. 2 times 2 = 4, and 7 times 2 = 14. 2 x 3 = 6, 7 x 3 = 21 (etc).
