Answer:
X=35 Y=73
Step-by-step explanation:
use the opposite angle theorem for x. X would equal 35.
we know that x is 35. So 2y+35=180
180-35=2y
y=72.5 or 73
srry I can’t help with question 2. I don’t know how
Since a cube has 6 faces, just divide the total surface area by 6 to find the area of 1 face.
96 / 6 = 16
So, the answer is: The area of one face is 16 cm!
Answer:
x=-19 x=30
Step-by-step explanation:
-5x-15=-3x+23
-23 -23
-5x-38=-3x
+5x +5x
-38=2x
/2 /2
-19=x
-107-7x=73-13x
-73 -73
-180-7x=-13x
+7x +7x
-180=-6x
30=x
Ok, so area/width=length
then they gave you mixed fractions
they want you to practice converting mixed fractions into improper fractions and dividing them
rmember, improper fractions are a/b where a>b sometimes
and also remember that
![\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{ad}{bc}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%7B%5Cfrac%7Bc%7D%7Bd%7D%7D%3D%5Cfrac%7Bad%7D%7Bbc%7D)
okie dokie
width
4 and 1/2=width
4+1/2=width
8/2+1/2=width
9/2=width
area=36 and 3/4
area=36+3/4
area=144/4+3/4
area=147/4
so area/width=length
![\frac{\frac{147}{4}}{\frac{9}{2}}=length](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B147%7D%7B4%7D%7D%7B%5Cfrac%7B9%7D%7B2%7D%7D%3Dlength)
![\frac{(147)(2)}{(4)(9)}=length](https://tex.z-dn.net/?f=%5Cfrac%7B%28147%29%282%29%7D%7B%284%29%289%29%7D%3Dlength)
![\frac{294}{36}=length](https://tex.z-dn.net/?f=%5Cfrac%7B294%7D%7B36%7D%3Dlength)
![\frac{49}{6}=length](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B6%7D%3Dlength)
![\frac{48}{6}+\frac{1}{6}=length](https://tex.z-dn.net/?f=%5Cfrac%7B48%7D%7B6%7D%2B%5Cfrac%7B1%7D%7B6%7D%3Dlength)
![8+\frac{1}{6}=length](https://tex.z-dn.net/?f=8%2B%5Cfrac%7B1%7D%7B6%7D%3Dlength)
so the length is
1 and 5 are supplementary angles since they form a straight line
