Simplify the expression:
3(2 + 5r) =

6 + 15r

Step-by-step explanation:

you do the distributive property:

3 x 2 = 6

3 x 5r = 15r

and then put the expression back together

hope this helps:)

r = -6/15 is your answer.

Step-by-step explanation:

What yoy want to do is get r by itself.

3(2 + 5r) = You will times 3 by 2 and 5r to get

6 + 15r = You will then subtract 6 from both sides

15r = -6 You will then divide 15 by both sides to get

r = -6/15 is your answer.
