The value of 'n' when we solve n/7 = -3 is
Understand the Problem
The question asks to find the value of 'n' by solving the equation n/7 = -3. This involves isolating 'n' to find its value.
Answer
A) -21
Answer for screen readers
A) -21
Steps to Solve
- Solve for n in the equation $\frac{n}{7} = -3$
To isolate $n$, we multiply both sides of the equation by $7$: $$ \frac{n}{7} \times 7 = -3 \times 7 $$
- Simplify the equation
Simplifying both sides gives us: $$ n = -21 $$
A) -21
More Information
A Pythagorean triplet consists of three positive integers $a$, $b$, and $c$, such that $a^2 + b^2 = c^2$.
Tips
A common mistake is to divide instead of multiplying by 7 to isolate $n$. Another common mistake is to forget the negative sign.
