In total Anna and Ryelin have 985 songs downloaded.

Ivenika [448]

Subtract 985 from 177 since Anna has 177 more songs than Ryelin. Then divide that answer by 2 which gives each one an equal amount then add 177 to one of the answers to get how many each girl has.

$985 - 177 = 808$
$808 \div 2 = 404$
$404 + 177 = 581$
So Ryelin has 404 songs downloaded and Anna has 581 songs downloaded.

Two consecutive negative integers have a product of 12. What are the integers?

iVinArrow [24]

Well 12 = 3×4 thus answer would be -3 and -4

For algebra solution, we can let smallest integer be n then that would be n(n+1) = 12, so we can go ahead and solve for n:

n(n+1) = 12

n² + n - 12 = 0

(n-3)(n+4) = 0

n = 3 or -4

Since we need negative integers, n would be -4 and then next integer (n+1) would be -3.

Hope this helps.
