Question

is d = 10 a solution to this equation 12d = 490 yes no

Explanation:

Step1: Substitute d = 10 into the left - hand side of the equation

We have the equation \(12d = 490\). When we substitute \(d = 10\) into the left - hand side (LHS) of the equation, we calculate \(12\times d\). Substituting \(d = 10\), we get \(12\times10\).
\(12\times10=120\)

Step2: Compare with the right - hand side

The right - hand side (RHS) of the equation is 490. Since \(120
eq490\) (the LHS is not equal to the RHS when \(d = 10\)).

Answer:

no
