Question

There are 27 marbles in a blue jar. The blue jar has 9 times as many marbles as a red jar. Let n be the number of marbles in the red jar.

Answer 1

n = 2.7

Explanation:

1. Set up an algebraic expression: 9n + n = 27
2. Combine like terms: 10n = 27
3. Divide each side by 10 to cancel out the 10 next to n. It should now look like this: n = 2.7

I really hope this helps!
