To convert from degrees Celsius in degrees Fahrenheit, multiply the number by 9, divide by 5, and add 32. In this instance, 30 x 9 = 270 / 5 = 54 + 32 = 86.Therefore 30 degrees Celsius is equal to 86 degrees Fahrenheit.

56 ÷ 30 = 1 with remainder 26.Then, add a decimal after 1 and continue dividingAfter bringing down your zero it becomes 260Then you multiply 8x30 to make 240 which you subtract from 260After that you get 200, and then you use 6 again to make 180 to subtract it from 6.For you answer you get 1.86
30 / 2 + 10 - 2 = 23
Start with n, then you get; Add 17: n + 17 Double it: 2n + 34 Subtract 4: 2n + 30 Double it: 4n + 60 Add 20: 4n + 80 Divide by 4: n + 20 Subtract 20: n which is where you started.
subtract Example: $5 off $30 is $25

-add 3n to both sides -subtract 2 from both sides -cancel out the both -divide 28 by 7.
-3. 30/10x=0 <-Set up equation like this, then subtract 30 from both sides (10x=-30). Then divide both sides by 10 (x=-3).

Only once because after that, it is no longer 30.
