Answer: 105 = g
Step-by-step explanation: To get <em>g</em> by itself, we would multiply
both sides of the equation by 7.
On the left, (7)(15) IS 105 and on the right, the 7's cancel.
So we have 105 = g.
Answer: 20
Step-by-step explanation:
You find the mean by adding up all the numbers in a data set, then dividing by the number added.
18 + 15 + 22 + 18 + 25 + 19 + 23 + 20 = 160
We added 8 numbers together, so we divide 160 by 8
160/8 = 20
