In order to find the mean we have to first add the numbers up:
38+18.05+25+26+46=153.05
Then the next step is to know how many numbers we have (5 numbers)
the we divided the sum by the number of numbers:
153.05/5=30.61
so a) is the correct answer!
1. simplify 1/3 ( c + 1 ) to c + 1/3 ( c + 1 over 3 = 1/6 (3c - 5)
2. simplify 1/6 (3c - 5) to 3c - 5 over 6 ( c + 1 over 3 = 3c - 5 over 6 )
3. multiply both sides by 6 [The LCM of 3, 6] 2(c + 1) = 3c - 5
4. expand (2c + 2 = 3c - 5)
5. subtract 2c from both sides (2 = 3c - 5 - 2c)
6. simplify 3c - 5 - 2c to c - 5 (2 = c - 5)
7. add 5 to both sides (2 + 5 = c)
8. simplify 2 + 5 to 7 (7 = c)
9. switch sides (c = 7 )
so in conclusion the answer is 7.
To The bottom half it is B. 0.8(9+w) = 0.8w + 72 and 4.8 + 2.2w - 1.4w +2.4 = 0.8w + 72
Hope this helps sorry cant do other half
69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23
hope this helps
