<span>We are looking for the value of x if we know the value of y=0.8 and the equasion is: 4x + 8y = 40. First we separate what we don't know on the left side and what we do know on the right: 4x = 40 - 8y. we know y=0.8 so we put that in the equation and we get: 4x = 40 - 8*0.8. Now we have: 4x = 40 - 6.4=33.6. Finally, we divide the left side and the right side by 4 and we get: x=33.6/4=8.35. So x=8.35.</span>

Two integers, a and b have a product of 15. what is the least possible sum of a and b?
Neporo4naja [7]
If they're integers, that means they can't be fractions (such as 15/2 and 2).

So the only couples of integers that, when multiplied, result in 15 are:

1 and 15
5 and 3.

(there are no other possibilities as both 5 and 3 are not divisible further).
The smaller of the two sums (15+1; 5+3) is 5+3=8.

The least possible sum of a and b is 8.
