Answer:
30
Step-by-step explanation:
27, 28, 28, 29, 29, 29, 30, 30, 30, 31, 31, 31, 33, 34
Continuously cross one off from each side and get 30 and 30. The mean of these is 30.
75-60=15
40+15=55 so Annette is 55 inches tall
She needs to work 64 hours to earn 1 vacation day.
You get his by dividing 768 by 12.
If correct brainliest please.
Thank you.
Answer:
The value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
Step-by-step explanation:
Given the expression
solving
We know that the equations with infinitely many solutions have the same expressions on both sides
It means the value of k can be determined by further simplifying such as
8x+20-8x = k
20 = k
Therefore, the value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
VERIFICATION:
Given
Put k = 20 in the equation
equations with infinitely many solutions have the same expressions on both sides.
This means the statement is always true.
Answer:
x = 18
Step-by-step explanation:
Given
6 - x = - 12 ( subtract 6 from both sides )
- x = - 18 ( multiply both sides by - 1 )
x = 18
