How do you write an algebraic equation for the number of members divide by six is fifteen?

What is the y-90 decay equation in which zicronium-90 is produced?
90Y --> 90Zr + e- 90Zr, stable
What is the nuclear decay equation for strontium 90?
Since the atomic number of Sr is less than 90, Sr undergoes beta decay. Beta decay is when the element decays into another element and a neutron actually breaks apart (sort of) into an electron and proton; the proton attaches to the other element, but the electron stays alone. Thus: 90------>90 Y+e0-1 38 Sr--->39 Y+e *there should only be one e, and the 0 and -1 should be in front, just like with the elements, but the format deletes the extra spaces so i put it like that for clarity's sake. sorry!
What is decay product of Yttrium90?
Yttrium-90 (Z= 39, N=51) decays to Zirconium-90 (Z=40, N=50) by emission of a beta particle (Neutron - > Proton + beta minus). Zirconium-90 is stable.
What is the distance from Dekalb IL and Minneapolis?
About 370 miles following this route:Take I-94 EAST to Wisconsin where I-94 joins with I-90, and then eventually, I-39.Stay on I-39/90/94 to I-39/90.
