1. $2\cdot(8-3)-6=2\cdot5-6=4$

2. $14c-6=22\implies14c=28\implies c=2$

3. $2x+18=5x\implies 3x=18\implies x=6$

4. $18-c+9c+6=24+8c$

5. $8x=-56\implies x=-7$

Hope this helps :)

For the filming of a recent sci-fi movie, a model spaceship made to a scale of 1:16 was used. In the movie, the ship is supposed

Lunna [17]

Answer: 6.5 feets

Step-by-step explanation:

The model of the spaceship was made to a scale of 1:16. Assuming the same unit of measurement used in the actual spaceship was also used in the model space ship and it was in feets. This means 1 foot on the model spaceship represented 16 feets on the actual spaceship.

In the movie, the ship is supposed to be 104 feet long. Let x be the corresponding length on the model. Therefore,

1:16 = x:104

1/16 = x/104

16x = 104

x = 104/16 = 6.5feets

So the length of the model is 6.5 feets

$\bf recall\\\\
log_{{ a}}{{ b}}=y \iff {{ a}}^y={{ b}}\qquad\qquad 
{{ a}}^y={{ b}}\iff log_{{ a}}{{ b}}=y \\\\

\textit{so hmmm what would that be in log notation? }\ 5^y=x \iff \boxed{?}$
