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

Combine each pair of equations solve the combined equation 3j +14=-5z-10j=5z
ArbitrLikvidat [17]

Given data:

The first equation is 3j +14=-5z.

The second equation is -10j=5z​ .

Add both the equations.

\begin{gathered} (3j+14)+(-10j)=-5z+5z \\ -7j+14=0 \\ 7j=14 \\ j=2 \end{gathered}

Substitute 2 for j in the first equation.

\begin{gathered} 3(2)+14=-5z \\ 20=-5z \\ z=-4 \end{gathered}

Thus, the value of j is 2 and z is -4.
