<span>a) dollar markdown = price reduction = $74 - $48 = $26</span>
<span>b) percent markdown = (initial - final) / initial × 100% = 26/74 × 100% = 35.1%</span>
Translate into math language:
7 - 3x = 23→ -3x = 23-7 → - 3x = 16 and x = - 16/3
If the legs are length a and b and hyptonuse is c then
a²+b²=c²
so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
The answer is 5x - 9 = -30
