Answer:
468 minutes
Step-by-step explanation:
Given data
At a race a few months ago, she finished in 360 minutes
let us find 30% of 360 minutes
=30/100*360
=0.3*360
=108 minutes
Hence she finished with an added time of 108minutes
Therefore, in all she finished in
=108+360
=468 minutes
A would be 6/12 (1/2) and B would be 1/12. To make this easier to understand, think of it this way. 6+1=7, and 6-1=5. In the future, find what adds to 7 and begin plugging in numbers until you get the correct answer.
If the diagonals of the parallelogram intersect with each other, this means that the diagonals bisect each other. Thus,
AE = CE
Substituting the equations,
2x² - 3x = x² + 4
The values of x from the equation are equal to 4 and -1.
AE = 2(4)² - 3(4) = 20
Hence, AC is equal to 40.
Answer: 40 units
The answer that I got is C=-6
