6c - (3 – 3c) = 24<br> Solve equation step by step
kap26 [50]

Hi there! :)

\large\boxed{c = 3}

6c - (3 - 3c) = 24

Distribute the negative sign with terms inside the parenthesis;

6c - (3) - (-3c) = 24

6c - 3 + 3c = 24

Combine like terms:

9c - 3 = 24

Add 3 to both sides:

9c = 27

Divide both sides by 9:

c = 3.

Solve the logarithmic equation. Round the answers to the nearest hundredth. 6+In x=8
ahrayia [7]

Answer:

7.39 ( nearest hundredth )

Step-by-step explanation:

Using the rule of logarithms

log_{b} = n ⇔ x = b^{n}

Note that ln x represents log_{e} x

given 6 + ln x = 8 ( subtract 6 from both sides )

ln x = 2 ⇒ x = e^{2} ≈ 7.39
