-17 x -3 = 51
If x + 51 equals 17, then x must be negative. (If we are going to add 51 to some number and only get 17, an number less than 51, then we had to start at a negative number for this to happen.) Let's work through this one.x + 51 = 17x = 17 - 51 (we subtracted 51 from both sides of the equation)x = -34 (we have arrived at the answer)
The square root of 51 is an irrational number and it is about 7.14128429
Let's call the number x. x-25=-51. Add 25 to both sides. You get x=-26. The number is negative 26.
10 x tan(51) = 12.349 (rounded) tan(510) = negative 0.5774 (rounded)
