<h3>Answer:</h3>
- Calvin: incorrect, sign error
- Greg: incorrect, has no relationship to the given expression
- Ruben: incorrect, sign error
- Equivalent expresssion: 7 92(4x -11)
<h3>Explanation:</h3>
The two terms on the right, -8x and +22, have even coefficients, so a factor of 2 can be factored out. If we do that, then these two terms become ...
... 2(-8x/2 +22/2) = 2(-4x +11)
We could, instead, factor out -2 so the x-coefficient inside parentheses is positive:
... -2(-8x/-2 +22/-2) = -2(4x -11)
Note that the signs of the two terms inside parentheses are different no matter which way we do it.
<u>Equivalent expressions</u>
Calvin could have written: 7 -2(4x -11)
Ruben could have written: 7 +2(-4x +11)
Greg could have written: 8(2 -x) -1. He would have rearranged the expression to 16 -8x -1 before doing so.
Answer:
Choice D
Step-by-step explanation:
38/4 =9.5
Therefore, this number is between 9 and 10
Note:
38/4 = 9 remainder 2
Hence, the quotient is 9 which is a whole number
True. Math right to left would be absurd. Please Mark Brainliest!!!
Answer:
D
Step-by-step explanation:
the median is the middle value of a data set in ascending order
If there is not an exact middle then it is the average of the values on either side of the middle
Arrange data in ascending order
15, 17, 19, 21, 23, 25, 26, 28, 28, 30
the middle is between 23 and 25 , hence
median = 
= 
= 24
