230 per hour. multiply 230 by the number of hours to find total posters.
The equation is Total = 230 x hours written as T = 230x, where x is the number of hours.
you have the total, so replace t with the value and solve for x:
1265 = 230x
Divide both sides by 230:
x = 1265 / 230
x = 5.5 hours.

Mean is the average. To find the average, add the four scores together and divide by 4.
The expression is Mean = ( score 1 + score 2 + score 3 + score 4)/4
Replace what is known:
20 = (25 + 15 + 18 + p)/4
Simpligy:
20 = (58 +p) /4
Multiply both sides by 4:
80 = 58 + p
Subtract 58 from both sides:
p = 80 - 58
p = 22
1. 1/9 since you take all the "a"s in the words which is 2/18
2.2/9 same thing as above
3.18/18 since there is no "O" it's a trick question
4.3/9
5.5/6 since you don't count 6
6.1/2 and 1/2 coins are always 1/2 unless you flip twice
7.5/13
8.1/2 because 1,3,5 odd 2,4,6 even
Hope that helps
512=2w^2 is the best answer
