9514 1404 393

Answer:

106

Step-by-step explanation:

Each of the whole numbers could be 4 greater than the value it is rounded down to. Then the maximum original sum is ...

90 +4 +4 +4 +4 = 106

<em>Example</em>

The numbers could be 14, 24, 34, 34. Their rounded values are 10, 20, 30, 30, for a total of 90. The total of the original numbers is 106.

Depends on the question...

If your question is 2/3b + 5 = 7, then follow this one
$\frac{2}{3}b + 5 = 7\\\\\sf You~ first~subtract~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~\frac{3}{2}~on~both~sides.\\\\ So...\\\\ \frac{2}{3}b + 5 - 5 = 7 - 5\\\\\frac{2}{3}b = 2\\\\\frac{2}{3}b \times \frac{3}{2} = 2 \times \frac{3}{2}\\\\b = 3$
Your final answer will be b = 3

If your question is 2/3b - 5 = 7, then follow this one
$\frac{2}{3}b - 5 = 7\\\\\sf You~ first~add~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~\frac{3}{2}~on~both~sides.\\\\ So...\\\\ \frac{2}{3}b - 5 + 5 = 7+5 \\\\\frac{2}{3}b = 12\\\\\frac{2}{3}b \times \frac{3}{2} = 12 \times \frac{3}{2}\\\\b =18$
Your final answer will be b = 18
