ANSWER

$log_{15}( {2}^{3} ) = 3 \: log_{15}( {2} )$

EXPLANATION

According to the power property of logarithms:

$log_{x}( {y}^{n} ) = n \: log_{x}( {y} )$

The given logarithm is

$log_{15}( {2}^{3} )$

When we apply the power property to this logarithm, we get,

toni can carry up to 20lbs in her backpack. her lunch weighs 0.75lbs, her gym clothes weigh 2.3lbs,and her books b weigh 3.4lbs

Oxana [17]

let her lunch = l, her gym clothes = g, her books = x

20 pounds is the amount she can carry

her lunch (1) weighs 0.75 lbs

her clothes (1) weighs 2.3 lbs

her books (x) = 3.4 lbs

Set the inequality

3.4x + 2.3 + 0.75 ≤ 20

Simplify

3.4x + 3.05 ≤ 20

3.4x + 3.05 (-3.05) ≤ 20 (-3.05)

3.4x ≤ 16.95

3.4x/3.4 ≤ 16.95/3.4

x ≤ 4.99 (rounded)

x ≤ 4.99 can be one of your inequalities.

her books can weigh up to 4.99 pounds before her backpack breaks

hope this helps
