Answer:
17
Step-by-step explanation:
The diagonals in a parallelogram bisect each other, creating two equal halves. So HV = 1/2 of XV
HV = XV/2
HV = 34/2
HV =17
Convert each fraction so they both have a common denominator by finding the lowest common denominator.
The lowest common denominator of 6 and 8 is 24. 8 goes into 24 3 times and 6 goes into 24 4 times.
now convert the fractions: 7/8 = 21/24
and 5/6 = 20/24
Now subtract:
21/24 - 20/24 = 1/24
Pam walks 1/24 of a mile more.
Total = green marbles + red marbles + blue marbles
55 = 15 + 12 + blue marbles
55 = 27 + blue marbles
55 - 27 = blue marbles
28 = blue marbles
Answer:
110
Step-by-step explanation:
A quadrilateral's angles always add up to 360 degrees. This is because a triangle has 180 degrees, and a quadrilateral can always be split into two triangles.
This said, we can set up the following expression:
40+128+82+x=360
168+82+x=360
250+x=360
x=110
