1 = Not Possible
2 = Not Possible
3 = Not Possible
<span>4 = 2 + 2 </span>
<span>5 = 2 + 3 </span>
<span>6 = 3 + 3 </span>
<span>7 = 2 + 5 </span>
<span>8 = 3 + 5 </span>
<span>9 = 2 + 7 </span>
<span>10 = 3 + 7
</span>Taking into account that there must be two "Different" prime numbers, that leaves <span>5, 7, 8, 9, and 10. So 5 of the first 10 whole numbers.</span>

Consider the following equation, bh+hr=25 when solving for r
Komok [63]
Solve for r.

You want to get r by itself on one side on the equal sign.

bh + hr = 25

Subtract bh from both sides.

hr = 25 - bh

Divide h on both sides.

r = 25 - bh / h

The two h's cancel each other out.

r = 25 - b

Hope this helps!
