Answer:
Add all the values up and divide by 7 ( as there are 7 values in the data set)
Step-by-step explanation:
1.9 + 10 + 11 + 16 + 12 + 12 + 14 = 76.9
If you divide by 7, you will get 10.9857142857.
Answer: I think it’s 225
Explanation: 1,500 • .15= 225
There are a number of expressions that are equivalent to 10a+6.
To find them, you simply have to list the multiples of both 10 and 6.
10- 10 20 30 40 50 60 70 80 90 100
6- 6 12 18 24 30 36 42 48 54 60.
Then, when you multiply the fraction by anything, whether this is 2, 3 or 10, you just have to do this to both parts.
All of the following expressions are equivalent to 10a+6
20a+12, 30a+18, 40a+24, 50a+30, 60a+36, 70a+42, 80a+48, 90a+54, 100a+60
Or, if you're looking to simplfy, then you have to find a common multiple, which is 2. Therefore, 2 goes outside of the bracket, and you then have to divide 10 by 2 to find out what goes inside the brack. 10a/2= 5a. 6/2=3, therefore, in a bracket, it becomes 2(5a+3)
Hope this helps :)
Answer:
2: x=6
3: x=5
Step-by-step explanation:
Question 1 is answered in the picture, but the answer is 6
<h2>Question 2:</h2>
x=14.3-(6.3+2)
x=14.3-8.3
x=6
<h2>Question 3:</h2>
x=20.6-(8.6+7)
x=20.6-15.6
x=5
