104 minus 13 is 91.
137 - 35 = 102
240 - 137 = 103
160 - 104 = 56
104 - 26 _____ 078
It is: 275-104 = 171
600 - 104 = 496
Whenever you minus a negative (number), you add. So it would be 104 - (-13), or 104 + 13, which is 117
The differencs is 240 minus 137 equals 103
An equation to find the value of the variable 104, 137, 154 and x with a mean of 130 is: (104 + 137 + 154 + x)/4 = 130 395 + x = 130 * 4 x = 145.
Beta minus decay emits a positron so a proton is changed to a neutron in this process. This means that caesium 137 decays to Xenon 137
