Answer:

-8/7 =x

Step-by-step explanation:

-2 x+1

----- = -----------

12 x+2

Using cross products

-2 (x+2) = 12 (x+1)

Distribute

-2x -4 = 12x+12

Add 2x to each side

-2x+2x -4 = 12x+2x+12

-4 = 14x +12

Subtract 12 from each side

-4-12 = 14x

-16 = 14x

Divide each side by 14

-16/14 =14x/14

-8/7 =x

2x = 32

2x/2 = 32/2 ..... dividing both sides by 2

x = 16 which is the answer

Gre4nikov [31]

Answer: The required two number will be 247 and 248.

Step-by-step explanation:

Since we have given that

Number of people at the Cineplex on last Saturday=1486

Number of theaters are there=6

Number of people in each theatres is given by

$\frac{1486}{6}=247.66$

So it must lie between 247 and 248.

As the number of people in each theatre is 247.66 so , it may be between 247 and 248.

So, the required two number will be 247 and 248.
