Answer:

error in step 1

Step-by-step explanation:

\frac{1}{2} (x + 18) = 4(2x - 6) - 9x

Multiply through by 2 to clear the fraction

x + 18 = 8(2x - 6) - 18x

[ Eleanor made the error in not multiplying - 9x by 2 ] ← ←

x + 18 = 16x - 48 - 18x

x + 18 = - 2x - 48 ( add 2x to both sides )

3x + 18 = - 48 ( subtract 18 from both sides )

3x = - 66 ( divide both sides by 3 )

x = - 22

laila [671]

Answer:

0.9

Step-by-step explanation:

To find the mean temperature, we have to add all of the numbers together and divide that by the amount of numbers there are.

6 + 5 + 3 + -4 + 3 + -3 + 2 + -1 + -2 + 0 = 9

There are 10 numbers.

Our mean, or average, would be 9 / 10 = 0.9
