The answer would be about 5.8
Let the number x.
Then the number divided by 2 gives
![\frac{x}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D)
Subtract 3.8 from the quotient gives
![\frac{x}{2}-3.8](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D-3.8)
Hence,
![\frac{x}{2}-3.8=7](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D-3.8%3D7)
![\begin{gathered} \frac{x}{2}-3.8=7 \\ \frac{x}{2}=7+3.8=10.8 \\ \Rightarrow x=2\times10.8=21.6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7Bx%7D%7B2%7D-3.8%3D7%20%5C%5C%20%5Cfrac%7Bx%7D%7B2%7D%3D7%2B3.8%3D10.8%20%5C%5C%20%5CRightarrow%20x%3D2%5Ctimes10.8%3D21.6%20%5Cend%7Bgathered%7D)
x = 21.6
Answer:
31:150
Step-by-step explanation:
First of all we convert the hours into minutes:
5×60=300
which gets us 42:300, which we can simplify to:
31:150
and is 31 is prime and 150 can't be divided into it without a remainder, it is in it's simplest form and it is the answer.
The better buy would be the 36 bottles of water for 4$ because it would be 9 bottles per dollar other than the 24 which is 8 bottles per every dollar. Hope it helps!
X and Y are vertical angles, which mean they are the same.
The 3 inside angles need to equal 180 degrees, so solve for X:
X = 180 - 35 - 65 = 80 degrees.
Y = 80 degrees.
