To find those equations we can do any multiplication or division of both sides of the equation:
Examples:
2x + 9 = -15 | · 2
4x + 18 = -30
2x + 9 = -15 | · (-1)
-2x - 9 = 15
2x + 9 = -15 | ÷ 2
x + 4.5 = -7.5
There is the same solution: x = -12.
So 1 hour= 60 minutes
60+25= 85 minutes
Now we should subtract the 42
85-42=43
It's diameter is 17.98. (I'm pretty sure I'm right I even used a calculator, if not sorry)
