Answer:
20
Step-by-step explanation:
The given relation can be written as the 2-step linear equation ...
(1/3)n +2 1/3 = 9
n +7 = 27 . . . . . . . . . step 1: multipy by 3 (makes the coefficient = 1)
n = 20 . . . . . . . . . . . step 2: subtract 7 (separates variable from constant)
The number is 20.

<em>Additional comment</em>
Usually it is convenient to do the two steps in the opposite order: get the variable term by itself, then make its coefficient 1. Here, we chose the order we did because it eliminated fractions from the problem, which is often a step you'd like to do first.
Answer:
13.4 left
Step-by-step explanation:
Answer:
1 ten and 3 ones
Step-by-step explanation:
ten + three is 13. Hence, one ten and three ones.
Area = 80 sq yards
height = 10 yards
80 = .5* 10 * base
base = 16
The smallest number would be 4
the three numbers would be 4, 10, and 14, which would have a sum of 28
