Solve the equation. 5d = 17.1 12.1 22.1 85.5 3.42

Hello!

Explanation:

Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

a/c=b/c for c≠0

First, you divide by 5 both sides of an equation.

5d/5=17.1/5

And then, simplify.

17.1/5=3.42

=3.42

The final answer is d. 3.42. *The answer must be have a decimal point.*

Hope this helps!

Thanks!

Have a great day!
