Answer:

x = 3

Step-by-step explanation:

6x+ 5 = 3x + 14

Subtract 3x from both sides

6x+ 5 -3x = 3x + 14 - 3x

Simplifying

3x + 5 = 14

Subtract 5 from both sides

3x + 5 - 5 = 14 - 5

Simplifying

3x = 9

Divide both sides by 3

3x/3 = 9/3

Simplifying

x = 3

Answer:

x=3

Step-by-step explanation:

First, you need to take 3x from both sides.

6x+5-3x=3x+14-3x (3x+5=14).

Next, subtract 5 from both sides.

3x=9

Finally, divide each side by 3.

3x÷3=9÷3 (x=3).

18y-18 + 6y = 180<br> What does this equal

muminat

Answer:

y = -16.5

Step-by-step explanation:

18y - 18 + 6y = 180

-18y - 18 + 6y (-18y) = 180

-18 - 12y = 180

+18 - 12y = 180 (+18)

-12y = 198

198/-11 = -16.5

Write an equation with the solution x=25.The equation should have the variable on both sides,a decimal coefficient on the left s

Ostrovityanka [42]

$x=25\ \ \ \ \ |add\ 5x\ to\ both\ sides\\\\6x=25+5x\ \ \ \ \ |multiply\ both\ sides\ by\ 0.25\\\\\boxed{1.5x=6.25+1.25x}\\\\check:\\1.5x=6.25+1.25x\ \ \ \ \ |subtract\ 1.25x\ from\ both\ sides\\\\0.25x=6.25\ \ \ \ \ \ |divide\ both\ sides\ by\ 0.25\\\\x=25$

Two weeks ago, Alice came home from vacation and noticed that a bean plant was growing in her garden. Today, the stalk is $452$

dimulka [17.4K]

So, on day 1, the plant was say "P" cm tall.

then 2 weeks go by, or 14 days, and the plant grew to 452 cm.

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=P(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\to 452\\
P=\textit{initial amount}\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
t=\textit{elapsed time}\to &14\\
\end{cases}
\\\\\\
452=P(1+0.05)^{14}\implies \cfrac{452}{1.05^{14}}=P$
