L=N (because opposite angle of parllalogram is euqal)
4X-25= 3X+18
X =43
there for angle N=3×43+18
N=147
Now we know that the sum of the corresponding angle of a parllalogram is 180
N+M=180
M=180-147
M=33
In simplest form, both top and bottom number cannot be divided into any smaller numbers. So, the calculation would be:
6/9 x 3/8
=(6x3)/(8x9)
= 18/72 ............................Divide both by 18
= 1/4
Answer:
question 1. 32 shelves
question 2. $27.25 for each card
Step-by-step explanation:
question 1. 567÷18 equals 31.5 but that won't make sense to just cut a shelf in half so Marcy will need 32 shelves
question 2. A dozen equals to 12. In this instance it equals 12 cards so $327÷12 equals $27.25
X^2 - 4x + 2
d = b^2 - 4ac, where a = 1, b = -4 and c = 2
d = (-4)^2 - 4 x 1 x 2
d = 16 - 8
d = 8
