Suppose that a, b, and c are digits for which the number
708,16b,8c9 is a multiple of 99. Find a+b+c.
There is no way to determine a because you have provided no mathematical statement in which it appears. Perhaps you copied the question incorrectly. This is the second time you have posted this, and my response is the same.
my teacher gave it to me an i strictly copied an pasted. i think that i have to solve the equation using algebra.by finding the value for A,plug in in an so forth..is that right???
I think your teacher made an error in the assignment. It doesnt make sense. You can't ask for an "a" value if there is no place to put it in the number.
