Answer:

<h3>X=4.8</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

x/-12=-0.4

x(-12)/-12=(-0.4)(-12) (First, multiply by -12 from both sides.)

(-0.4)(-12) (Solve.)

(-0.4)(-12)=4.8

x=4.8

So, the final answer is x=4.8.

An N-scale model railroad caboose is 3 inches long. N scale is 169 feet to 1 foot.
hammer [34]

9514 1404 393

Answer:

  • c/3 = 169/12
  • 42 1/4 feet

Step-by-step explanation:

Since we want to know the actual number of feet, we can write the proportion with that in the numerator.

  \dfrac{\text{actual feet}}{\text{scale inches}}=\boxed{\dfrac{c}{3}=\dfrac{169}{12}}\\\\c=\dfrac{3\cdot169}{12}=42\frac{1}{4}\qquad\text{multiply by 3}

The real caboose is 42 1/4 feet long.

9 + 11 > 8 (true)

Thus 8,9 and 11 can be construct as a triangle.

b.
4 + 5.1 > 12.5 (false)
4 + 12.5 > 5 (true)
12.5 + 5 > 4 (true)

Thus, 4, 5.1 and 12.5 cannot be constructed as a triangle.
