<u> P = 2 (L + B)</u>
Divide each side by 2 : P/2 = L + B
Subtract B from each side: <em>P/2 - B = L</em>
(Are you saying the king case is an additional 12% of $84? I think you should word the question a bit more clearly).
12% = 12/100 = 0.12 multiplied by $84 = $10.08 = $84 + $10.08 = $94.08
We have $94.08 so far (king case and camera price combined).
Tax is 6%, so 6/100 = 0.06 multiplied by $94.08 = $5.64
Add $5.64 to the $94.08 total we calculated.
$94.08 + $5.64 = $99.72 <=== this is our total cost plus tax.
Mm i think 7 you just have to divide like the number by 2 like 40 divided by 2 is 20 then divide the 20 and you get 10 idk
Expand
(4a + 12 = 12 + 4a)
Cancel 4a on both sides
12 = 12
Since both sides are equal there are infinitely many solutions
Process of elimination, cross out d) no solution. But I would best go with C)
78 could be seventy-eight, 78 over 1, and 78/1.
