Solve 5(2x + 4) = 15. Round to the nearest thousandth.<br> PS: x+4 is the power for 2
lilavasa [31]

\qquad \qquad\huge \underline{\boxed{\sf Answer}}

Let's solve for x ~

\qquad \sf  \dashrightarrow \: 5(2x + 4) = 15

\qquad \sf  \dashrightarrow \: (5 \times 2x) + (5 \times 4) = 15

\qquad \sf  \dashrightarrow \: 10x + 20 = 15

\qquad \sf  \dashrightarrow \: 10x + 20 - 20 = 15 - 20

\qquad \sf  \dashrightarrow \: 10x =  - 5

\qquad \sf  \dashrightarrow \:  \dfrac{10x}{10}  =  \dfrac{ - 5}{10}

\qquad \sf  \dashrightarrow \: x =   - \dfrac{ 1}{2}

hence value of x is - 1/2

SOMEONE PLS HELP WHAT DO I DO HERE
pav-90 [236]

Answer:

see below

Step-by-step explanation:

4 ^(3x-1)=3

Take the natural log of each side

ln(4 ^(3x-1))= ln (3)

We know that ln ( a^b) = b ln a

(3x-1) ln 4 = ln 3

Divide each side by ln 4

3x-1 = ln(3)/ (ln4)

Add 1 to each side

3x = ln(3)/ ln (4) +1

Divide by 3

x =1/3 [( ln 3)/ ln (4)] + 1/3

x = .792461
