5/x = 2/21
Answer: x = 52.5
16/21 minus two equals -1 5/21
21/x = 105/5 = 21 21 = 21x x = 1
x/5 = 8/21 x = 8/21 * 5 x = 1.904761905
it equals 21
Unfortunately, 2 over 2 minus 1 equals 5 over 6 is just a wrong answer! If it is 2 over 2, minus 1, the answer is that it equals zero. If it is 2, over 2 minus 1, the answer is that it equals 2.
1 and 2/5
0.4
20/21
21 -2*5 +3 +10 = 24
x-2/3 = 0x - 5/7 = 0(x-2/3)(x-5/7) = 0x^2 -2/3(x) -5/7(x) + 10/21 = 0x^2 -14/21(x) - 15/21(x) +10/21 = 0x^2 -29/21(x) +10/21 = 0Another Answer:-If: x = 2/3 and x = 5/7Then: (3x-2)(7x-5) = 0Multiplying out the brackets: 21x2-29x+10 = 0 which is the equation.Check using the quadratic equation formula: x = 2/3 and x = 5/7
It is: 10/2 = 5
It equals 2 and 2-fifths. Or 2 and 2 out of 5. Or 2 and 2 over 5.
