Answer:

x=15

Step-by-step explanation:

\frac{1}{3}  \times (x + 9) = 8 \\  \frac{x}{3}  +  \frac{9}{3}  = 8 \\  \frac{x}{3} + 3 = 8 \\  \frac{x}{3}  = 8 - 3 \\  \frac{x}{3 }  = 5 \\ x = 3 \times 5 \\ x = 15

Find the mean of 81, 97, 99, 89, 91, 76 (round to the hundredths)
Marta_Voda [28]

Answer:

88.83

Step-by-step explanation:

To solve for the mean you have to add all of the values together and divide that sum by the number of values there are.

Ex. 81, 97, 99, 89, 91, 76

     81 + 97 + 99 + 89 + 91 + 76 = 533

     533 / 6 = 88.83

               ↓
