The <em>correct answer</em> is:
Her number is 7.
Explanation:
Let x represent her number.
She triples her number; this is represented by 3x.
She then adds 5 to this; this gives us 3x+5.
She gets 26 aas her answer. This gives us the equation:
3x+5 = 26
To solve this, first subtract 5 from each side:
3x+5-5 = 26-5
3x = 21
Divide each side by 3:
3x/3 = 21/3
x = 7
N-2=10n+42
Add 2 to both sides
n=10n+44
Subtract 10n from both sides
-9n=44
Divide both sides by -9
n=(-44/9)

Hello,
y=35*6^x
==>ln(y)=ln(35)+x*ln(6)
==>e^ln(y)=e^(ln(35)+x*ln(6))
==>y=35*ln(6)*e^x≈62.711*e^x
