For this case we have the following equation:

6x + 5 = 5x + 8 + 2x

We must find the solution.

We add similar terms from the right side of the equation:

6x + 5 = 7x + 8

We subtract 5 from both sides of the equation:

6x = 7x + 8-5\\6x = 7x + 3

We subtract 7x on both sides of the equation:

6x-7x = 3

Different signs are subtracted and the sign of the major is placed:

-x = 3

We multiply by -1 on both sides of the equation:x = -3

Thus, the solution of the equation is x = -3. -5 is not a solution to the equation.

Answer:

x = -3. -5 is not a solution to the equation

Answer: Infinite solutions.

Step-by-step explanation:

y=-2x-6\\2y=-4x-12

Plug the value of y into the second equation.

\\ 2(-2x-6)=-4x-12\\-4x-12=-4x-12

Add 12 on both sides.

-4x-12+12=-4x-12+12\\-4x=-4x

Add 4x on both sides.

-4x+4x=-4x+4x

Answer:

sorry to answer late but..

Step-by-step explanation:

\frac{1}{75} cm = \frac{scale }{real}

the wings of the real plane are 12 meters or 1200 cm

we want to solve for the scale, sooo do the algebra...get scale by it self..

real * \frac{1}{75} = scale

1200 * \frac{1}{75} = 16

The scale model wings are 16 cm   2.54 cm is one inch so the wings are approx.  6.3 inches

Answer:

Runner 1 has the fastest pace

Step-by-step explanation:

The first one we need to find the slope

m = (y2-y1)/(x2-x1) = (40-0)/(4-0) =40/4 = 10 minutes per mile

The second  is 8.5 minutes per mile

The third we need to find the slope

m = (y2-y1)/(x2-x1) = (90-72)/(10-8) =18/2 = 9 minutes per mile
