Well this equation should look like 40=1/2p this means we have to get p by itself inorder to do that we have to divide p and 40 by 1/2 or 0.5. why divide well because in order to get rid of a multplication you have to divide and why do it to both sides because everything you do to one side you have to do to the other when you divide 40 by 0.5 you get 80, no if you want a fraction you will have to set 40 over 1 to get a fraction as well to be able to simplifyit this gives you 40/1 divided by 1/2 find a common dinominator for 1 and 2 well it can be 2 so lets multiply 1 times 2 to get 2 and 20 times 2 to get 80 now we have 80/2 and 1/2 now multiply them to get 80/2. now when you divide this does it give you 40?? it does so we have found the right answer
Hope this helps
The residuals of any data set should get added to zero. If there are three residuals (say A, B, and C) in any data set, then it could be written as A + B + C = 0.
Given are the two residuals -10 and -20 out of three point in a particular data set.
Let's assume A = -10 and B = -20, so that we could find third value C of the given data set.
We know A + B + C = 0
(-10) + (-20) + C = 0
(-30) + C = 0
C = 30
It means that third residual must be 30.
Hence, the final answer is 30.
Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
