PLS help<br> solve for x: -6(2x-5) = 18
Mashutka [201]

Hey!


-6(2x-5) = 18


Switch it around and it becomes:


2x - 5 = 18 \div -6


First find 18 ÷ -6


18 \div -6 = -3

Positive ÷ negative OR negative ÷ positive is always negative.


That leaves you with:


2x - 5 = -3


Switch that around and it becomes:


-3 + 5 = 2x


Find -3 + 5


-3 + 5 = 2


That leaves you with:


2 = 2x


Divide both sides by 2 to leave <em>x</em> alone


\frac{2}{2} =  \frac{2x}{2}


\framebox{x = 1}

Convert 510° from degrees to radians
vitfil [10]

Answer:

\frac{17\pi }{6}

Step-by-step explanation:

To convert from degrees to radians

radian = degree measure \frac{\pi }{180}

           = 510 × \frac{\pi }{180}

           = \frac{51\pi }{18}

           = \frac{17\pi }{6} radians

Please help me with this problem so I can better explain this to my son.2.Rhonda started a business. Her business made $30,000 i
4vir4ik [10]
\begin{gathered} a)P=30000(1+0.05)^n \\ b)\$62,367.00 \end{gathered}

1) Iteration means a repetition of a rule.

a)

Considering that we have the following data:

Rate of increase: 5% per year

-

2) Then we can write out the following:

P=30000(1+0.05)^n

Plugging into n, the number of years we'll have:

Profits: $30,000 1st year

P: $31.500 2nd year

$33075 3rd year

(...) (...)

b) Since we want to know the predicted profit 15 years from the first year, then we can plug for that:

\begin{gathered} P=30000(1+0.05)^{15} \\ P=\$62,367.00 \end{gathered}

Note that we have plugged into n, n=15 years. Since the first year was $30,000 the profits.
