Answer:
13
Step-by-step explanation:
2(x – 3) + 3y
Let x=5 and y = 3
2(5 – 3) + 3*3
Parentheses first
2(2) +3*3
Multiply
4+9
Add
13
9x8-[18+(15+60/4)]+10
First, solve the inner parentheses:
(15+60/4) 60/4= 15
15+15= 30
Next, add the 18 and the 15, since they are still inside the parentheses:
18+15= 33
9×8-(33)+10 Is what we're left with.
Multiply: 9×8= 72
72-(33)+10
Subract: 72-33= 39
Add: 39+10= 49
The simplified answer is 49.
To find the mean. You would add up all the numbers then divide by how many numbers there are.
2.02+24.6+2.88+2.18+2.78+2.35+2.22= 39.03
39.03/7=5.5757
ANSWER: 5.5757
