Question

1. \frac{n - 12.9}{6.1} = -0.37

Explanation:

Step1: Rewrite the equation

The given equation is $\frac{n - 12.9}{10}=- 0.37$. Multiply both sides by 10 to eliminate the denominator.
$n - 12.9=-0.37\times10$

Step2: Calculate the right - hand side

Calculate $-0.37\times10=-3.7$. So the equation becomes $n - 12.9=-3.7$.

Step3: Solve for n

Add 12.9 to both sides of the equation: $n=-3.7 + 12.9$.
Calculate $-3.7+12.9 = 9.2$.

Answer:

$n = 9.2$
